Marine Officials Say they have received reports of at least a half dozen other sites. Beyond the criminal investigation, pentagon Officials Say this scandal could do real marm harm to the military by convincing young women not to join or convincing those already in uniform to get out. Scott. Pelley david martin breaking the story from the pentagon tonight. David, thank you. President trump has been hold up in the white house all week not taking one question there reporters since he accused president obama of wiretapping his phones. Twice this week, White House Events scheduled to include reporters have been closed at the last minute. It was saturday that President Trump accused his predecessor of committing a crime that he said was equal to watergate. Mr. Trump said, it is a fact that his phones were tapped in the latter days of the campaign. It is true that the f. B. I. Has been investigating communications between Campaign Officials and russian operatives. No one has been charged with a crime. Yesterday, our Margaret Brennan asked the white house whether mr. Trump is the target of an investigation. The president s spokesman came up with two answers, and today, a third. Reporter press Secretary Sean Spicer said that the white house is still not sure whether or not the president is under investigation. Im not aware of it. But thats not point is that were not aware of anything. Reporter so youve never been told by the Justice Department there is no investigation. No. Reporter so there might be one. You just dont know. Right, i said were not aware and im not aware. Reporter the Justice Department said they never gave you the assurances that you gave us. No, the assurance i gave you, margaret, is im not aware. If somebody asks me if im aware of something and i say no the answer is no. Reporter the would appear inappropriate if he did ask for answers. Members of congress have contacted the bureau for information as part of a taxpayerfunded probe. Republicane graham its not to much to ask the department of justice and the f. B. I. Whether or not a warrant was sought and issued. Reporter attorney general Jeff Sessions recused himself last week from any trump campaignrelated investigations. Before that, he had rebuffed calls to appoint a special counsel for an independent probe, but today, he said he might consider one to investigate obamaera scandals. Im going to do everything i possibly can to restore the independence and professionalism of the department of justice. So well have to consider whether or not some outside special counsel is needed. Reporter today, f. B. I. Director jim comey briefed key members of the house and senate, each for about an hour, on these wiretapping allegations, and the Ongoing Investigation into russian contacts with trump advisers. Scott. Pelley but no word on what came out of those meetings yet. Margaret brennan, thanks. Today, want founder of wikileaks bragged to repor after exposing c. I. A. Methods for hacking phones, computers, and other devices. He spoke via streaming video from Ecuadors Embassy in london where he has been living as a fugitive from justice since 2012. Jeff pegues has more on this. This is historic act of devastating incompetent of tense. Reporter in a nearly hourlong presentation, wikileaks founder, julian assange, railed against the c. I. A. For failing to protect its secret Cyber Espionage tools. The Central Intelligence agency lost control of its entire Cyber Weapons arsenal. Reporter wikileaks says it obtained the information from socalled gray hat hackers, contractors who work for u. S. Intelligence. The 8,000 stolen documents detailed c. I. A. Tools to penetrate smartphones, smart te systems. In a statement today, a c. I. A. Spokesman said that assange was not a bastion of truth and integrity. Yesterday, the agency said the disclosures jeopardizize u. S. Personnel and operations. The c. I. A. Was aware weeks before tuesdays disclosure that valuable information may have been stolen. The f. B. I. Is now work with the c. I. A. To determine not only who stoalt information but whether another country like russia was involved. Jim lewis consults with the u. S. Government and military about cybersecurity. Theres good data that suggests ties between assange and the Russian Security services. And theres very strong data that wikileaks has a powerful antiamerican agenda. Reporter wikileaks says it is reaching up on the to Companies Like microsoft, apple, and google so they can fix the hacking vulnerabilities. Scott, they all say they are working on close loopholes they already know about. Pelley jeff pegues, today, President Trump said despite what you hear in the press, health care is coming along great. Well, what youve heard in the press is tha that a. A. R. P. , ande American Medical Association are against the republican replacement for obamacare, and so are conservative republican senators who say the house bill should be scrapped. We asked Dean Reynolds to find out what mr. Trumps supporters think. Reporter jim monosas lawnmower and snowblower business in racine has hit some hard times. The lack of snow this winter for one thing and obamacare for another. It seems like were working seven days a week and we dont have any more to show for it. Reporter though he has private Health Insurance for himself and his workers, monosa says theres been a Ripple Effect to rising costs for obamacare that has made his coverage more expensive, too. We were just working to pay off the like. I mean, something has to change. Reporter Trump Supporters, like monosa, said obamacare is a mess, but at franks diner down the road in kenosha, larry rafng was not confident a replacement would be an improvement. But it shhh it be replaced . No ping we should try to work within it, and make changes to it. I dont think we have to necessarily replace it. All right reporter everyone we spoke to felt Congressional Republicans are running up against the reality that health care is complicated. Dick gentz is an accountant. From what it sounded like to me is they really couldnt pull the plug on it entirely. Reporter at the counter, glenn woods said its time for the republicans to act. When you run on one thing more than anything else and you have the power to change it, you Better Change it. Reporter woods and the other Trump Supporters said the protracted health care tugofwar has not their regard for the president. How do you think the president s doing . Too early to tell, honestly. I mean, its hard to turn around an aircraft carrier. Reporter is he headed in the right direction . Yes. Reporter in fact, the people we spoke to, scott, seemed much more patient with President Trump than with their own republican congressman who happens to be the speaker of the house, paul ryan. Pelley Dean Reynolds as we continue to listen to the people. Dean, thank you very much. Mr. Trumps new head of the e. P. A. Broke with science today to say that he is notquenced that Carbon Dioxide from cars, trucks, and power plants is driving the rise in global temperature. Heres chip reid. Reporter scott pruitt, the new head of the e. P. A. , dropped a verbal bomb on the Environmental Community today saying this about the role of Carbon Dioxide emissions in Climate Change so, no, i would not agree that its a primary contributor to the to the that we see. Reporter its not the first time pruitt has hinted hes a Climate Change denier. Last year, he wroapt that the debate is far from settled. But he seemed to change his tune during his confirmation hearing last month when he was asked if he agreed with President Trump, who called Climate Change a hoax on the campaign trail. I do not believe that Climate Change say hoax. Reporter todays apparent change of heart, infuriated environmental groups. The sierra club said the arsonist is now in charge of the fire department. Brenda ekwurzel is director of the Climate Science with the union of concerned scientists. If you were talking to mr. Pruitt right now, what would you tell him . Listen to the scientists. 97 of scientists who have studied Climate Change agree that Carbon Dioxide is the primary cause of humandriven Climate Change. Reporter in january, nasa reconfirmed that rising Global Temperatures are driven largely by increased Carbon Dioxide and other humanmade emissions into the atmosphere. And this is still on the of pruitts e. P. A. , Carbon Dioxide is the primary Greenhouse Gas that is contributing to recent Climate Change. Pruitts comments appear to be a sign of things to come. Scott, the Trump Administration is preparing to roll back Obama Administration regulation thagz limit c. O. 2 emissions from cars and power plants. Pelley chip reid, thanks. Today, the head of u. S. Forces in the middle east, general joseph votel, told senators that more american troops are needed to beat isis in syria. Thats on top of 400 that recently joined u. S. Special Operations Forces backing a mission to retake raqqa, the isis capital in syria. The u. S. Is also supporting iraqi forces in their fight to liberate the city of mosul from isis, and Holly Williams is on the front line. Reporter mosul is the people of this oncewealthy city fled with their bundles of possessions, sometimes with just the clothes on their backs. A part of the world so ancient, its mentioned in the bible, now brought tots knees. In al dawasa neighborhood, around 150 yards from the front lines, Muhammed Yunus made it to safety with his young family. He told us isis fighters are hiding in peoples homes. Including four in his before it was hit by a mortar. As the iraqis claw back one street at a time, isis has smashed its way from house to house, so its fighters can move without being detected from the sky. Iraqi forces claimed theyd recaptured mosuls main government building on tuesday, but today, we couldnt get within a block of it. Told us isis is still sniping at his men, contesting every inch of territory, even as its forced to retreat. And when isis is finally pushed out of mosul, which could be in weeks, scars will remain. Hassan alley fled the city with his wife and five children. But told us they had to leave behind the body of his father after he died a week ago. The u. S. Has spent around 12 billion combating isis in iraq and syria, and, scott, americas top general in the fight recently predicted that both mosul and raqqa, the extremist stronghold in syria, would be recaptured within six months. Pelley Holly Williams with the battle of mosul. Holly, thank you. Coming up next on the cbs evening news, impostor fraud. Well tell you how to spot a phony.

I literally was about to hang up when they said, are you at this address . And it was my p. O. Box that ive had for many, many years. Reporter the man on the other end said he was Sergeant Wade mawcialg withlet Sheriffs Department and tanner owed fines of 1600 for failing to appear for jury duty. He immediately launched into this very polished siewnding i mean, very authentic sounding speech about were calling you as a courtesy. You have several outstanding citations. Reporter attorney told him he had instructed tanner to pay up immediately or face a warrant for his arrest. The call went on for nearly 40 minutes on his landline before tanner used his cell phone to call the local Sheriffs Department. The first thing i said was, is there a Sergeant Wade marshall . And i barely got the words out when the real Sheriffs Department said,no, its a scam, hang up. Law enforcement would never make such a request Jeter John Bolden says its a growing problem nationwide. The scammers are extremely well versed in the judicial process. They have frequently used real judges names, real names of u. S. Marshal service employees. Theyve even spoofed telephone numbers that are real telephone numbers to federal courts and to u. S. Marshal service offices. Reporter monica vaca is with the federal trade commission. There are probably a lot of people out there hearing this saying, i wouldnt fall for that. But the fact. Matter is when you get one of es real. Scammers are very, very good at making you believe that youve got an emergency situation on your hands, and they have a really powerful way of getting you to act on that.

Reporter these elite canine drogz trained to immediately sniff out the poacher, rushing to attack, pinning him to the ground, until more help arrives. This may be a training exercise, but the dogs bites are real and special biteproof suits are needed.

In the past seven years alone, a third of africas elephants have been wiped out. Nearly 100 of these sky diving dogs have been placed in game reserves across africa.
