"Are you going to take the tweets literally?"
The Russian government has rejected accusations by USA intelligence agencies it worked to influence the election in Trump's favour.
But White House spokesman Sean Spicer defended Trump's assertion, citing media reports that have discussed intelligence collection on possible contacts between Trump associates and Russian Federation in the campaign. The FBI is also investigating. After missing a deadline set by Nunes and Schiff, the department asked for more time to review their request and "to determine what if any responsive documents may exist".
The Justice Department missed a Monday deadline for providing the information to the House and was given a one-week extension.
Reuters reported earlier this week that an unidentified British security official had denied the allegations about Trump. Stone communicated through Twitter direct messages with Guccifer 2.0, a hacker who has claimed responsibility for breaching the Democratic National Committee.
The Republican operative has acknowledged having a Twitter exchange with Guccifer 2.0, a hacker that USA officials believe has ties to Russian Federation. He said he would be "submitting certain things" to a congressional committee and that he was considering speaking about the topic next week.
Justice Department spokeswoman Sarah Isgur Flores said in a statement to CNN that the department "has complied with the request from leaders of the House and Senate Intelligence Committees and Judiciary Committees seeking information related to surveillance during the 2016 election".
Senator Mark Warner, the committee's Democratic vice chairman, said he had "grave concerns" about the independence of the committee's probe after the report that Burr had helped the White House dispute the stories.More news: Which Box Office Records Did 'Beauty and the Beast' Smash?
Identities of Americans who show up in USA surveillance against foreign entities are supposed to stay concealed. Those include situations when the communications contain information that a crime has been or is about to be committed; when the Americans' identity is necessary to understand the importance of the foreign intelligence collected; or when the communication provides information that an American may be an agent of a foreign power.
In a statement, Nunes said the committee still had not received information it requested from the Federal Bureau of Investigation and Central Intelligence Agency about whether information collected on USA persons was mishandled and leaked to the public. After Michael Flynn resigned as Trump's national security adviser because of his calls to Russia's ambassador, Chaffetz said his panel would not look into the issue. Asked Wednesday if he had ever briefed Trump on the investigation or given the president any reason to believe he had been wiretapped by the Obama administration, Sessions said, "The answer is no".
White House spokesman Sean Spicer said the president stands by his claims.
"I've been reading about things", Mr Trump said.
The Russian government has rejected an accusation by United States intelligence agencies that it worked to influence the election in Mr Trump's favour by hacking computer systems, among other methods.
An official familiar with the investigations by Congress and intelligence and law enforcement agencies said investigators had looked as aggressively and thoroughly as they could for evidence of any spying on Mr Trump or his associates but had found none.
"We're not here to listen to speeches", Nunes said.
