represented the finest in our country. davon mckenzie wasff-duty riding a motorcycle when an impact stru him and sent him intoi incom traffic. he was just 24 years old. police have identified one of the drivers killed in a wrong way wreck in brandywine. one person died after another driver hit his car head-on. police have not identified that other driver, trying to figure out why that person veered into oncoming traffic on brandy wine road. robert mueller spoke for the irst time today about his investigation. he resigning special counsel said he could not charge president trump with a crime because of justice policy. he also said he could not clear mr. trump of obstruction of justice. >> thank you, erica. robert mueller's statement is creating quite the buzz throughout washington. >> a lot of republicans are saying the russia probe should now just end. more democrats are calling fori eachment procedures. >> nbc news senior political editor, mark murray, is tracking today's reaction to the breaking news. mark, for you, what was the ak meggest te away from mueller's surprise announce today? >> number one, we finally heard his voice, which was something over this last two years, oh, that's what he sounds like. to me, the biggest headline ofh ever was his statement that today, this was also mentioned in the mueller report as well but he forcefly said if we had evidence that the president did not commit crimes would havesaid that. that's an indirect roundabout way of saying, hey, there ishi somet there there when it comes to obstruction situation. because of department of justice regulations you can't necessarily charge a sitting president. thirdly, most importantly, it goes to congress, has to be the ones deciding this.p this does the ball in n ncy pelosi's court. we're already seeing democratic presidential candidates weighin in, yes,u need to begin impehment proceedings now. what was extraordinar was once again mueller raising his voice, if i could have exonerated the president, i would have de so. >> why didn't he come out and say that in those words? >> sometimes a lawyer wants to be very precise with his or her own language,yalwas, mueller has been incredibly cautious. this stands out when i was covering the ken starr bill clinton imeachment, not as cautious and conservative, go-go go, charge charge char, the big starr report that came mueller has been incredibly cautious throughout. today, what he ended up sying i thought was once again very cautious but still packs a ve powerful punch because of the way, if you want to think critically what he is saying, ngy, coss, there is something for you to investigate. >> where does it go from here? now.'s in congress's hands one of the criticisms house speaker nancy pelosi continues to get there still is no north star what they're investigating. you have different committees investigating different things. deep down, pelosi also knows if this goes to the senate. imachment is a two-step process. the house brings the procedures and th it's up to the senate tot acqui or convict the president. they don't have the numbers now. if the house goes its way and senate being controlled by republicans, all right, now, the president is exonerated, that actually could end up,ruresident tmp saying, see, i was exonerateds[v i thinkat th is what nancy pelosi and democrats are thinking about, if they godown this road you need results to win. >> democrats wanted to hear from him but want to hear from him in another setting. it doesn't sound like he wants to testify. do you think the democrats will call him? >> we got a statement from house intelligence committee chairman adam schiff w says he wants to hear from mueller. ine other take away from mueller, pleadwith congress, i don't want to speak anymore. if you ask me to speak, all i am going to say is the exact same thing today. we're kind of back at square one. >> we know no more. >> put on your magician's haho does the president twist this to turn it into a positive for him? how could he take what we heard today and turn that into mplete exoneration, no wecollusion? e already hearing the white house secretary sarah sanders saying exactly that. mueller said there was no llusion or obstruction, move on. that is te ofhe weaknesses from this muellerdirect position, the direct message t fromhe president, even though se it's fal, packs even a bigger punch than what mueller is saying being so indirect and cautious. >> i wonder why he came out to say what he said without saying mething. >> to be continued. >> good to see you. >> "nightly news" with lester holt will have much more on robert mueller's statement and reaction from republicans an democrats. tune in at 7:00 tonight right after
