News World Headquarters in new york, this is nbc nightly news with lester holt. Good evening. Interest questions surfaced about the source of the intelligence that landed in President Trumps lap last week, but he quickly sees as partial vindication of wiretap claims.

The congressmans whereabouts the day before he dropped the bombshell are fueling suspicions among democrats. Nbcs Hallie Jackson with what we know tonight. Reporter tonight, a new plot twist in the surveillance saga consuming congress and the white house. If this was a movie, you turn it off because you wouldnt believe its believable. Reporter the latest bombshell coming from devin nunez, the republican head of the House Intelligence Committee that revealed u. S. Spies may have swept up communications involving the trump transition team. Its called incidental collection and while nunez said there is no evidence to back the president s claim trump tower was wi wiretapp wiretapped, President Trump felt vindicated anyway. I somewhat do, i must tell you i somewhat do. I much appreciated the fact they found what they found. Reporter turns out, one day before he briefed the president , nunez was on white house grounds reviewing the secret information from the secret source. The congress has not been given this information, these documents. There is no way for the folks that i have been working with to actually to bring this forward to light. There was no way i could view that because they couldnt get it to the house intelligence committ committee. Reporter nunez looked at the reports in the in the west wing but a special secure room a few hundred feet away. You cant walk on the white house grounds, go on to a secret room and log on a computer unless someone on the white house staff allows you to. Reporter its not a staffer but a member of the intelligence community. They arent worried about an inappropriate leak. Is this leak but other leaks are not . I think there is a difference between a leak and someone pursuing review of a situation, someone who is clear to share classified information with somebody else cleared is not a leak. Reporter but democrats are concerned about the coincidental timing with more questions on whether nunez can be impartial as he leads one of the congressional investigations into russias interference with the election. Chairman nunez is falling down on the job and seems to be more interested in protecting the president than in seeking the truth.

But behind the scenes mounting urgency for a win, the target now tax reform an already daunting task made more difficult after members of his own party the conservative Freedom Caucus defying the president refusing to back the health care bill. Does the president still believe he can work with the Freedom Caucus on the legislation . I think its going to depend on the legislation. Not necessarily . No, i dont think i think as he mentioned, he learned a lot through this process about loyalty. Reporter now the president signaling hell look to democrats but after months of personal insults and finger pointing. I think the losers are nancy pelosi and Chuck Schumer. I noticed Chuck Schumer yesterday with fake tears. Reporter what incentive do democrats have to work with him. The one thing the white house can do to attract democrats is offer them something they want. There are tangible thi things to do to strengthen obamacare and infrastructure. Reporter still, the white house isnt ready to pull the pull on health care reform. The president will revisit the issue when obamacare explodes, independent Fact Checkers argue thats over stated but acknowledge the plan could see real problems next year. The big issue, many Health Insurers across the country are pulling out giving consumers fewer options and driving up the prices of premiums. At this Health Care Clinic in western ohio that sees more than 1700 patients per month, they are worried about the future of obamacare and the uncertainty surrounding all of it.
