FBI Deputy Director Andrew McCabe will be on Capitol Hill again to testify behind closed doors on Thursday, when he will likely be asked questions about the now-closed investigation into Hillary Clinton's private email server.

The Department of Justice told the chairmen and ranking members of both the House Judiciary and House Oversight committees in a Wednesday letter that McCabe will be available for transcribed interviews, according to a House aide. McCabe's testimony will be classified.

The Justice Department also made it clear that he will be unable to discuss matters within the scope of special counsel Robert Mueller's investigation into Russia's meddling in the 2016 election.

The House Judiciary and Oversight committees both announced in late October they were opening new investigations into the FBI's handling of its probe into Clinton's private email server, accusing the agency of letting the former secretary of state off easy.

Late Wednesday, committees' leadership asked McCabe and Attorney General Jeff Sessions that the former be available for an interview as early as Thursday. They also requested interviews with FBI chief of staff Jim Rybicki and Lisa Page, an FBI lawyer who traded anti-Trump text messages with a fellow member of the FBI, Peter Strzok, with whom she was working on Mueller's team.

Several Republicans have called for McCabe to be replaced or subpoenaed following the release of those text messages.

McCabe is also under investigation by the Justice Department's inspector general. That review was announced in May and stems from his wife Jill McCabe's campaign for a Virginia state Senate seat in 2015. Her campaign received donations from former Democratic National Committee Chairman Terry McAuliffe's super-PAC, as well as the Democratic Party of Virginia.

During that time, McCabe was running the FBI's Washington, D.C., field office, which was assisting the FBI's investigation into Clinton's email server.

Meanwhile, Republicans have pointed to the Page-Strzok text messages as evidence of bias on Mueller's team. Page and Strzok, with whom she was allegedly having an extramarital affair, have since been removed.

“McCabe cuts across every facet of every investigation in 2016 that your viewers are interested in, from Secretary Clinton’s emails to the investigation into the Trump campaign,” Rep. Trey Gowdy, S.C., told Fox News Tuesday.

Earlier this month, Gowdy told CNN, "The last couple of weeks have not been good. That group I'm in — that small group [of Republicans] that has supported Mueller and resisted calls for a special counsel — is getting smaller."

So far, Mueller has brought charges against four people part of the broad Trump investigation: George Papadopoulos, Paul Manafort, Rick Gates, and Michael Flynn.

McCabe testified before the House Intelligence Committee on Tuesday, specifically discussing the so-called "Trump dossier" and how the FBI used it during its own Russia probe.

McCabe served as acting FBI director between May and August after Trump fired James Comey. McCabe was reportedly considered to be the next director, but Trump ultimately chose Christopher Wray as his successor. McCabe was appointed by Comey in early 2016 to be deputy director of the FBI.
