Former FBI Director James Comey is "looking forward to having the opportunity to publicly share his thoughts and views" at Thursday's Senate Intelligence Committee hearing, Chairman Richard Burr said Monday.
Presidents can assert executive privilege to prevent government employees from sharing information.
Comey is scheduled to appear before the Senate Intelligence Committee on Thursday for his first public discussion of the events that led to his dismissal last month in the midst of leading an investigation into associates of Trump.
Comey, ousted last month amid a federal investigation into connections between Russian Federation and the Trump campaign, is set to testify before Congress next week in a highly anticipated hearing that could shed new light on his private conversations with the president in the weeks before the firing.

White House: Trump won't stop Comey from testifying
Comey's appearance will be carried on live television. And seeking to block Comey's testimony could amount to a grievous political misstep since it would instantly be seen as sign that the White House has something to hide.
Following Comey's firing last month, it was reported that he'd written memos about all of his meetings with Trump - and that during one, the president asked the FBI to drop its investigation of former national security adviser Michael Flynn.
While Some Republicans in Congress had said that Trump should stop Comey's testimony, many legal scholars believed Trump had already waived his executive privilege because he spoke about conversations he had with Comey and tweeted about them. Several investigations into Russia's meddling in the 2016 election are ongoing.
Some critics of Trump have said that such a request, especially given that he later fired Comey, could be interpreted as an obstruction of justice.
Former acting Attorney General, however, has testified that Flynn's conversation with Russian ambassador Sergey Kislyak was not accurately disclosed to members of the Trump White House - potentially opening himself up to blackmail.
