Man leading Russia links investigation says he has ‘duty and obligation’ to Donald Trump

“I felt I had a duty and obligation to tell him [Mr Trump] because as you know he’s been taking a lot of heat in the news media,” Mr Nunes told Fox News.

He added: “I think to some degree there are some things that he should look at to see whether in fact he thinks the collection was proper or not.”

Minority leader in the House of Representatives, Nancy Pelosi, expressed concern about Mr Nunes, who was a member of Mr Trump’s transition, admitting to feeling a “duty and obligation” to someone he is supposed to be investigating.

“I think he sent a signal that as a member of the Trump transition team himself, he probably should not be intricately involved in this investigation,” Ms Pelosi said at a news conference on Thursday.

She added that he was either “duped” or a “willing stooge” of the White House and called on an independent committee to investigate Russian meddling into the election.

Although Mr Nunes has found Mr Trump’s claims he was wire-tapped by the Obama administration to be complete baseless.

But Mr Trump has claimed Mr Nunes’ briefings helped him feel “vindicated”.
