The Latest on former FBI director James Comey (all times EDT):

8:15 p.m.

A person familiar with the situation says former FBI Director James Comey asked Attorney General Jeff Sessions to keep him from being alone with President Donald Trump.

The person, who was not authorized to discuss the matter by name and spoke on condition of anonymity, says the request was made because of concerns Comey had about Trump.

Comey is expected to testify before the Senate intelligence committee on Thursday about his encounters with Trump in the weeks before his May 9 firing, and his conversation with Sessions could come up at the hearing.

It was not immediately clear when the conversation occurred. But The New York Times, which first reported the request to Sessions, said it came after Trump had asked Comey in February to end an investigation into Trump's first national security adviser, Michael Flynn.

President Donald Trump has scheduled a speech addressing religious conservatives around the same time that former FBI director James Comey is expected to testify before Congress.

The Faith and Freedom Coalition's "Road to Majority" conference announced Tuesday that the president had agreed to address the annual gathering Thursday.

Faith and Freedom spokesman Lance Lemmonds says the president is expected to speak at 12:30 p.m. EDT.

Comey is scheduled to testify Thursday before the Senate intelligence committee beginning at 10 a.m. that day.

His appearance will mark Comey's first public comments since he was abruptly fired by the president last month.

Other speakers expected to address the Faith and Freedom event are Vice President Mike Pence, House Majority Leader Kevin McCarthy and Texas Sen. Ted Cruz.
