Fired FBI director James Comey set to testify June 8 on Russia

White House press secretary Sean Spicer referred questions about Comey's upcoming testimony to Trump's outside counsel while speaking to reporters on Wednesday.

The scope of Comey's testimony was not exactly clear, though Mueller was permitting him to speak publicly, an associate told the AP.

"The big story is the "unmasking and surveillance" of people that took place during the Obama Administration", Trump said in a tweet, one day after the committee's Republican chairman subpoenaed the CIA, FBI and National Security Agency amid complaints by Democrats that they were not consulted.

The Trump administration said his handling of the inquiry into defeated Democratic presidential candidate Hillary Clinton's emails was the reason for his dismissal.

His hotly awaited appearance on Capitol Hill comes as probes by the Justice Department and several Congressional committees have moved toward Trump's inner circle, with investigators said to be examining contacts between top White House adviser and Trump son-in-law Jared Kushner and Russian ambassador Sergey Kislyak.

The former NSA director had a remarkably short tenure.

"Subpoenas related to the "unmasking" issue would have been sent by Chairman Nunes acting separately from the committee's Russian Federation investigation". Any such requests undergo rigorous legal reviews, and USA officials have said all such requests under Obama, a Democrat, were conducted properly. Any such requests undergo rigorous legal reviews.

And the former FBI head is likely to get questions about what exactly Trump told him about the investigation into former National Security Adviser Michael Flynn.

On Wednesday, the House of Representatives Intelligence Committee authorised subpoenas for Mr Flynn and Mr Trump's personal lawyer, Michael Cohen.

The committee's ranking Democrat, Rep. Adam Schiff of California, said Nunes approved the unmasking subpoenas without consulting the Democrats on the committee. Nunes retained his power to issue subpoenas.

Trump drew criticism for removing Comey from his position while Comey was leading an active investigation into Russia's role in the elections as well as possible ties to members of Trump's campaign.

Putin has denied conducting such a campaign.

Mr Trump has backed Mr Nunes' efforts to investigate actions by USA security and other officials who had served under previous president Barack Obama.

"We will continue to pursue this investigation wherever the facts may lead". He was Federal Bureau of Investigation general counsel under Mueller and began his career with the Justice Department in 1991 at the U.S. Attorney's Office in the Eastern District of NY.
