Former FBI Director James Comey will testify before the Senate Intelligence Committee next week, the committee announced Thursday.

He will testify first in an open session on Russia's meddling in the 2016 election at 10 a.m. Thursday, June 8, and a closed session will follow.

During his testimony, Comey is expected to say President Trump pressured him to end the FBI's investigation into ties between Trump's campaign associates and Russia, it was reported Wednesday.

Comey's testimony is highly-anticipated, as he led the investigation into Russia's meddling in the 2016 election before Trump fired him last month.

Following Comey's firing, several news reports revealed details of various interactions the former FBI director had with the president.

During one such interaction occurring days after his inauguration, Trump reportedly asked Comey to pledge his loyalty to him. Comey declined, but promised to always be honest with the president.

In another conversation, Trump reprotedly asked Comey to end the FBI's investigation into former national security adviser Michael Flynn, who was fired in February.

Comey recorded his interactions with Trump in memos while working at the FBI, and the details of those memos — including his conversations with Trump — are expected to be discussed during his testimony before the Senate Intelligence Committee.

The details of Comey's memos have caused concern among lawmakers on Capitol Hill, particularly Democrats, who are questioning whether Trump attempted to obstruct the Russia probe.

After Comey was fired, the Justice Department appointed former FBI Director Robert Mueller to serve as special counsel and oversee the probe.

Though some lawmakers were initially concerned that Mueller's appointment would prevent Comey from testifying privately, Comey and Mueller met privately to discuss how Comey could testify and avoid "legal entanglements."
