The powerful images playing out today. And of course, the other headline, the test within the Republican Party over what to do about congresswoman Marjorie Taylor greene, who has questioned whether parts of 9 11 happened and has suggested the parkland massacre, the sandy hook shootings, were staged. Those moving images, though, first. This began last night after the news, straight into the night and all day today, honoring Capitol Police officer Brian Sicknick, Lying In Honor inside the capitol. Only the fifth person to do so. Officer sicknick dying of injuries he sustained while defending the capitol, defending lawmakers, during the siege. President biden and first lady dr. Jill biden paying him tribute. And then there this late today. Republicans holding a high stakes meeting over one of their own, representative taylor greene. But republicans, we have learned, have decided late today, and this is all moving, but so far, to allow her to keep her posts. So, whats next . Democrats now forcing a vote to make sure republicans are on record on this. We have it all covered tonight, beginning with that debate within the Republican Party. And we begin here with rachel scott up on the hill again tonight. Reporter tonight on capitol hill, a moment of reckoning forr Marjorie Taylor greene, who has promoted a series of outlandish say ho a paranscol shootings were staged. Congresswoman, what is your message to your party . In the past, the Georgia Congresswoman expressed support for the false Conspiracy Theory qanon. And in 2019, she implied House Speaker nancy pelosi should be executed. Its a crime punishable by death is what treason is. Nancy pelosi is guilty of treason. Reporter she has even speculated a plane never flew into the Pentagon On 9 11. Its odd theres never any evidence shown for a plane in the pentagon. Reporter after suggesting those School Shootings were staged, she later harassed Teenage Parkland survivor david hogg when he traveled to washington, d. C. To lobby for gun control. And yet youre attacking our second amendment. Reporter still, even after all that, House Republican leader Kevin Mccarthy gave greene seats on the house education and budget committees. Democrats say thats nuts. Kevin mccarthy should handle this problem, because Marjorie Taylor greene is totally out of control. Reporter and its not just democrats. Senate republican leader Mitch Mcconnell attacking greene, saying, loony lies and Conspiracy Theories are cancer for the Republican Party and our country. The antisemitism, School Shootings werent real, i mean, she runs the gamut. The idea that forest fires are started by jewish lasers, i mean, its just so profound, so far out there, i mean, it does make me wonder how she got elected. Reporter but congresswoman greene does have one very powerful republican in her corner former president donald trump. Marjorie taylor greene. I love Marjorie Taylor greene. Reporter and that has put House Republicans in a bind, as they met tonight to decide whether to strip away greenes committee assignments. Ultimately, they decided not to. In a statement, republican leader Kevin Mccarthy saying he had spoken to greene and she recognized that her past comments now have greater meaning. Will you apologize for any of our past statements . Greene herself taking nothing back. Recently tweeting, i wont back down. Ill never apologize. So, lets get right back up to rachel scott, shes on the hill again for us tonight. And rachel, we learned that late today, House Republicans were meeting about this. So far, they have decided not to committee assignments. Womans that still potentially could change. Youre going to follow this into the night. But what we do know, the full house, republicans and democrats, will have to vote on this. Democrats calling that vote. They have the majority, so, bottom line, whats going to happen here . Reporter well, david, this vote will be key, because its going to put republicans on the record. They are going to have to decide whether or not to look past greenes comments or whether to split from their party. As you said, bottom line, democrats have majority in the house, so, if all of them stay united and vote against her, she will be stripped of her committee assignments. And rachel, as you know, this is a split screen of sorts, because House Republicans tonight are also debating the fate of one of their highest ranking members in the house, congresswoman liz cheney, after backlash over her vote to impeach president trump. Of course, she was one of the ten republicans in the house joining democrats, facing that backlash for standing up to the president. The former president now. After what she saw at the capitol . Reporter shes the number three republican in the house and immediately after her vote to impeach, we saw the backlash. Some of trumps staunchest allies in the house demanded she be removed from party leadership. Tonight, republican leader Kevin Mccarthy is defending her. He says she has a right to vote her conscience and congresswoman liz cheney has no regrets. She says she will not apologize for her vote to impeach, david. The struggle within the party tonight.

David, sources t enfoement has been working to identify surveillance and witnesses that will give details on sicknicks confrontation with that mob. We still dont have an official cause of death from the coroner. David . Pierre thomas with the moving images of this day. Pierre, thank you. Of course, all of this comes amid growing concern over extremism here in the u. S. And tonight, defense secretary lloyd austin has now ordered a servicewide standdown for what he says are, quote, needed discussions on extremism within the u. S. Military. So, i want to bring in abcs martha raddatz, following this for us tonight. And martha, what prompted the sweeping move . Reporter david, White Supremacist groups have long targeted the military, but pentagon officials were alarmed that nearly 20 veterans were among those arrested after the siege on the capitol. They include two air force, eight marine corps, six army and two navy veterans. Had been out of the military for many years, two were current Army Reservists and one national guardsman. But there were no active duty troops. So, over the next 60 days, every unit in the military will have discussions with all of the forces about extremism. But the Pentagon Spokesman acknowledged today, david, they really dont know the extent of the problem. It could be better than they think, but it could also be worse, david. All right, martha raddatz, who has covered the pentagon for years for us. Martha, thank you. We turn now to the coronavirus here in the u. S. , and news this evening on yet another potential vaccine tonight. This one from astrazeneca. So, whats different about it . Could it not only help protect you, but could it, at some point, Stop Transmission of the virus . What dr. Anthony fauci is saying about that tonight. And heres abc now. Reporter tonight, promising vaccine news. Uk scientists finding the Oxford Astrazeneca vaccine likely not only protects people from the virus but also has the potential to reduce transmission. Now, that is really good news. Its very positive, because we know the vaccine is the way out of this. Reporter oxfords early data, not yet peer reviewed, revealing a single vaccine dose was 76 effective at protecting against the virus for up to three months. That protection increasing to 82 with a second shot given after a new, longer 12week interval. The study also suggesting that the vaccine can reduce the spread of covid by as much as 67 after one dose, suggesting those vaccinated are unlikely to infect others. Today, the white house cautiously optimistic. I havent seen the data yet. If thats true, thats good news, you know, yet again, another Vaccine Candidate in the mix. Reporter but Reminding Americans that the current vaccines in the u. S. Allow for a gap between doses of 21 days for pfizer or 28 days for moderna. To a week or two, i dont think thats a big problem, as the cdc says. But id be concerned about delaying it for three months or so. Reporter in new york, a Race Toetacckfter that the Javits Center increasing the number of appointments to 2,200 today to get ahead of a backlog. You said you felt a sense of urgency to get the vaccine . I couldnt wait to get the vaccine. Ive been trying so hard not to get this disease, its terrible. Reporter but those more contagious variants still top of mind for Health Experts here. Im not an alarmist, but this is as scared as i have been since the beginning of the pandemic. Reporter earlier this week, we introduced you to 35yearold a. J. Jackson in alabama. He had the uk variant. He hadnt traveled. Tuesday night, the father of two passed away. It was very hard to come to terms with that, but i had to go ahead and tell her, you know, daddy became an angel, just like granny, and she immediately hit the floor, started crying. It was just so bad. Reporter and a new study found that adults between the ages of 20 and 49 were more than 70 responsible for the spread in the virus in the u. S. Last year. David . All right, eva pilgrim with us again tonight. Thank you, eva. Were going to turn next here this evening to an abc news investigation. Two former nfl players speaking for the first time on camera about their time in the league, saying they experienced concussions and now suffer from depression, memory loss and bouts of anger. Two players suing the league, claiming the nfl uses a formula that assumes black players start at a lower cognitive level than white players, making it harder for black former players to qualify for compensation. Tonight, how the league is now responding. And heres abcs ryan smith. Look out. Down he goes reporter ev played eight seasons in the nfl. Thats a good, clean hit. Reporter tonight, he is accusing the league of what he says is a doublestandard when it comes to race and the concussion settlement. Im banged up. Im beat up. And the part that you dont see is up here. You dont see how my brain is beat up. They dont hit me less or harder because im black. Reporter kevin henry and rp najeh davenport, are suing the nfl, accusing them of avoiding paying headinjury claims based on a formula that discriminates on the basis of race. The formula, they say, assumes black players start at a lower cognitive level than white players, making it harder for black former players to qualify for compensation. Its a controversial practice called race norming, in which test results are adjusted to account for supposed differences between demographic groups. Theres the assumption that people of different races, especially black people, that their bodies function differently. Reporter and while the nfl insists the formula is optional, an abc news investigation has found that some clinicians who evaluate former nfl players believe they are required to apply the formula. Football doesnt give you an expiration date, it just happens. You just expire. Ive had ten concussions or more and thats not even counting practice. Reporter after his time in the league, kevin henry says he began suffering from depression, memory loss and bouts of anger. In 2017, he underwent a series of tests. A doctor determining that henry was suffering from a cognitive decline consistent with mild dementia. So he submitted a claim to the landmark 2013 nfl Concussion Settlement Program. What was the result of the claim you filed . I was denied. Reporter the Claims Administrator stated that there were issues related to validity of the tests and asserted that the evaluation used inappropriate norms. The effect of using this race norm for the nfl is that it drastically limits the amount of damages theyre going to have to pay out. Reporter how did you react when you learned that there was a different standard being used for black players to get benefits as compared to white players . I felt so betrayed and i still feel that way. Reporter emails exclusively obtained by abc news appear to show several neuropsychologists who work with the nfl privately discussing the lawsuit. In this email, a clinician saying their required reliance on racial norms bottom line, do discriminate against black players. In a statement to abc news, the nfl calls the lawsuit entirely misguided. The league says that race norming, part of what they call demographic correction, is recommended but not required. And the Concussion Settlement Program was agreed to by all parties with the assistance of Expert Neuropsychological Clinicians and it relies on widely accepted and longestablished testing and scoring methods. Now 52 years old is it gone . Yeah. Reporter kevin henry says daily life is a constant struggle. It takes everything in me to keep from crying, man. I just want to be i just want to be looked at the same way as a white guy. So, lets bring in ryan smith tonight. And ryan, where does this lawsuit stand tonight . The case still being litigated . Reporter yes, david. The players tonight are waiting for a judges ruling on the nfls motion to dismiss the case. And david, as of now, the nfls received 3,000 claims for compensation and paid out about 1,200 of them to former players and their families, totaling about 800 million. But the nfl has repeatedly denied requests to release Demographic Data on those receiving settlements. David . This is really eyeopening. Ryan, thank you.
