Comey’s appearance will once again shift focus to a figure who has drawn ire from both Democrats and Republicans for his decisions in 2016 and has remade himself into one of Trump’s fiercest critics since the president ousted him as FBI director last year.

It comes after months of wrangling between House Republicans and Comey, who last week asked a federal court in D.C. to quash a subpoena issued by House Judiciary Committee Chairman Bob Goodlatte Robert (Bob) William GoodlatteNo documents?

Comey instead offered to testify publicly, arguing that otherwise GOP lawmakers would offer selective leaks that would fit their “corrosive narrative” of FBI bias against President Trump.

A judge was set to rule on whether the interview could be delayed before Comey, acknowledging he faced an uphill legal battle, struck a deal with House Republicans in which he will testify behind closed doors, with a transcript of the interview released within 24 hours of his interview’s completion. Goodlatte seemed to signal it could take longer, saying in a statement it would be released "as soon as possible" in the name of a "combined desire for transparency."

Lawmakers are keen on pressing the former FBI chief on several matters, including a draft letter Comey wrote exonerating Clinton months before concluding his investigation and his contemporaneous memos documenting conversations with Trump that were leaked to the press.

Lawmakers are likely to drill down on details from the report released by Justice Department Inspector General Michael Horowitz over the summer that was highly critical of Comey’s judgment during the heated presidential race.

The interview also comes days after Mueller filed a memo recommending no prison time for Trump’s one-time national security adviser Michael Flynn as a result of his “substantial assistance” in the Russia investigation.

The developments could revive interest in Flynn’s case.

Comey helmed the FBI at the time Flynn lied to investigators about his contacts with the Russian ambassador. The former FBI chief also testified before the Senate Intelligence Committee in June 2017 that Trump told him to let go of the investigation into Flynn before firing him, an allegation depicted in one of his memos that Trump denies. Mueller is said to be scrutinizing the events to determine if Trump obstructed justice.

Republicans and Democrats are expected to attend the interview, but it remains unclear whether it risks being sparsely attended given that the House recessed for the week following the death of former President George H.W. Bush.

The interview, slated to begin at 10 a.m., is likely to stretch on for several hours. Comey’s attorney David Kelley said he had received no “commitment on the length of the interview.”

While a Republican source told The Hill in October that the joint congressional probe was in its final stages, the November midterms imposed a hard deadline for Republicans to compel Comey and others to testify before losing their subpoena power come January. Goodlatte has also subpoenaed former Attorney General Loretta Lynch to testify, but it’s unclear when the interview will occur. A committee aide said Thursday that Lynch “is expected to come in for her interview before the end of this Congress.”

Comey has emerged as a key target among GOP lawmakers, who have called on him to testify for months.

But some committee lawmakers have said it would have been more important to squeeze in interviews with other key witnesses before the start of this Congress, a sign of tacit disapproval for the way Reps.

“I think it is much more important that we subpoena Rod Rosenstein to come in and answer questions about what he plans to do in taping the president of the United States than it is to hear testimony from Director Comey and Attorney General Lynch,” Meadows recently told The Hill.

Goodlatte and Gowdy did arrange for a closed-door interview with Rosenstein back in October that was limited to committee leaders, but were forced to postpone it at the eleventh hour. The meeting has not been rescheduled.
