Comey to testify to US Senate intelligence panel on June 8

The former NSA director had a remarkably short tenure.

The President said Mr Comey informed him three times that he personally was not under investigation.

Trump has maintained that he's not under investigation and that there was no collusion between his campaign and Russian Federation during the election. But Trump himself has repeatedly said that the Russian Federation probe was on his mind when he removed Comey.

Representative Jim Himes, a Democrat on the House Intelligence panel, replied to Trump's tweet, calling it a "pathetic distraction".

The White House has denied those characterizations. Trump has alleged that Obama administration officials, for political reasons, asked to know the identities of Americans whose names are masked in intelligence documents.

A senior Republican staffer on the committee said Nunes signed the subpoenas for Flynn, Cohen and their companies, which were requested by Conaway and Schiff.

Russian President Vladimir Putin on Thursday again denied state involvement in any U.S. election cyber-attacks, but admitted "patriotically minded" hackers might have been involved.

Trump, a Republican, has denied any collusion between Russian Federation and his campaign and has repeatedly questioned the USA intelligence finding that Putin led an operation that included computer hacking, fake news and propaganda meant to swing the election in his favor.

White House press secretary Sean Spicer said inquiries about the Russian Federation investigation must be directed to Trump's longtime personal attorney, Marc Kasowitz. Also, the U.S. Department of Justice recently appointed a special counsel.

Former FBI Director James Comey plans to confirm reports that President Donald Trump pressured him to drop an investigation into former national security adviser Michael Flynn's ties to Russian Federation in congressional testimony, CNN said on Wednesday, citing an unidentified source close to the issue.

Comey reportedly wrote in a memo that Trump asked him to shut down the FBI's probe into former national security adviser Michael Flynn, who is also one of Trump's top aides during the campaign.

Meanwhile on Thursday, two Democratic senators, Patrick Leahy and Al Franken, issued a statement calling the Federal Bureau of Investigation to provide information on alleged meetings that Attorney General Jeff Sessions had with Russian officials past year and that were not reported by Sessions.
