"I don't think there was an actual tap of Trump Tower", he told reporters at the Capitol, and he said that if Mr. Trump's allegations are taken literally, then "clearly the president was wrong". White House spokesman Sean Spicer said that Mr. Trump didn't believe that Mr. Obama had personally tapped his phone, but instead was talking broadly about surveillance.
Donald Trump originally claimed that Trump Tower had been subject to wiretapping by Obama (or at the orders of Obama) in a stunning slew of tweets in early March.
A number of high-level officials have pushed back against those claims despite the White House's insistence that evidence of such wiretapping exists. In the meantime, it has asked the Department of Justice to turn over any evidence it has on Trump's allegation this month that he was wiretapped ahead of the election. He added that they still expect the Department of Justice to respond to a letter they sent asking from them to hand over any information about wiretaps before 20 March.
He did, however, say that he was concerned that some of Trump's associates may have been surveilled in other ways and that their names were leaked to the press. "Neither of us think this will be necessary, certainly, at the open hearing that we have on March 28, we'll be asking the director if he has seen any evidence that substantiates the president's claim". Graham has previously said he would use subpoena power to get information from the Federal Bureau of Investigation about whether a warrant was issued allowing the Obama administration to tap Trump's phones during the campaign.More news: Third of west Mosul retaken
Mr Nunes said the committee was battling with the Office of the Director of National Intelligence to get access to computer technology so they can go through CIA evidence on alleged Russian interference in the election. The FBI is investigating Trump associates' contacts with Russian Federation during the election, as are House and Senate intelligence committees. The claim, presented without evidence, was met with immediate skepticism from lawmakers questioning what the Republican meant.
"Um, look, um, answer's no", he said.
Nunes and Schiff also said the Intelligence committee has asked the FBI, CIA and the National Security Agency to turn over the names of any US citizens who may have been ensnared by surveillance eavesdropping and then had their names leaked.
"He feels very confident that what will ultimately come of this will vindicate him", Spicer said.
