Public testimony by the former FBI director could mark another major development in the controversy engulfing the Trump administration about past contacts with Russian officials - and whether the president or White House officials took steps to try to squelch the investigation.
Trump has also interviewed former Rep. Mike Rogers, R-Mich., who has been endorsed by the FBI Agents Association, and Frances Townsend, the homeland security and counterterrorism adviser to Bush.
CNN reported that Comey is unlikely to want to discuss any details into possible collusion between Trump officials and the Russians - as he did during previous testimony. "And in fact, when I made a decision to just do it, I said to myself - I said, you know, this Russian Federation thing with Trump and Russian Federation is a made-up story".
A spokeswoman for Senate Intelligence Committee chairman Richard Burr told ABC News Wednesday afternoon "The Committee welcomes the testimony of former director Comey, but does not have an announcement to make at this time".More news: Gulf rift: The Iran factor

That's what Donald Trump will learn next week as the former FBI director plans to confirm that the President pressured him to end the investigation into Russia's ties with a top Trump aide. The memo "was part of a paper trail Mr. Comey created documenting what he perceived as the president's improper efforts to influence an ongoing investigation", according to The Times.
Whenever Comey does testify, it will be before the Senate Intelligence Committee.
In an Oval Office meeting with senior Russian officials soon after firing the Federal Bureau of Investigation chief, Trump called Comey a "nut job" and said firing the intelligence chief had relieved "great pressure" on him.
The White House did not immediately respond to Fox News' request for comment as to whether any of those candidates are still under consideration.
Former FBI Director James Comey is expected to appear before the Senate Intelligence Committee next month. Trump has decried the probe as a "witch hunt" pursued by Democrats who he said can not accept the results of the 2016 election.
