House intel chair was on White House grounds day before briefing Trump on alleged surveillance

It's not clear why Rep. Devin Nunes chose to go to White House grounds.

On Friday, Nunes backtracked on some of the claims he said earlier in the week regarding the documents he reviewed.

When asked if he could clarify whether Trump or his associates were monitored or simply mentioned in the intelligence reports, Nunes said he won't know until he receives all the documentation.

Nunes has not disclosed where he got the information from, not even to other members on the House Intelligence Committee.
