The House Judiciary Committee has issued a subpoena for former Attorney General Loretta Lynch along with former FBI Director James Comey over Hillary Clinton’s use of a private email server, according to a Thursday New York Times report.

Committee chairman Robert Goodlatte (R-VA) issued the subpoenas on Wednesday for closed door hearings before the Judiciary and House Oversight and Government Reform Committees. Comey is slated to appear December 3, Lynch December 4.

Comey has already taken to Twitter to object to the closed-door hearing, requesting that his testimony be public.

The Oversight Committee will also be looking into White House senior advisor Ivanka Trump’s usage of a private email address, as chairman Trey Gowdy (R-SC) has requested information and a briefing on the topic.
