Watch the Comey hearing here

WASHINGTON (NBC) -

The highly anticipated hearing will mark Comey’s first public appearance since reports that he authored memos as part of a paper trail documenting what he believed was a campaign to thwart his investigation into Russian ties to the Trump campaign.

All eyes will be on the former FBI director as he is expected to address his statements released on Wednesday about being pressured by President Trump into pledging his loyalty to him, dropping the FBI investigation against former National Security Adviser Michael Flynn and telling the public that Trump was not being personally investigated.

Trump officials have denied claims of obstruction of justice by the president, and when asked about Comey's upcoming testimony last Wednesday, Press Secretary Sean Spicer declined to answer and referred questions about the hearing to Trump's outside counsel.

After Trump abruptly fired Comey last month, his allies have told NBC News the former director is eager to tell his story.
