The Justice Department’s top internal watchdog is headed to Capitol Hill Monday, to field questions from senators about his 500-page report examining the FBI investigation into Hillary Clinton’s private email server.

The hearing is scheduled to begin at 2 p.m. EST. Watch it in the player above.

Inspector General Michael Horowitz, who released the report last week, will testify before the Senate Judiciary Committee alongside FBI director Christopher Wray.

The report from Horowitz’s office sharply criticized the decision by Wray’s predecessor, James Comey, to work around top-level Justice Department officials and announce his conclusion in July 2016 that the Clinton investigation should be closed without pursuing criminal charges. While the report said there was no evidence to suggest that Comey’s decisions were the result of bias, it still faulted Comey for an “unjustified usurpation of authority.”

The wide-ranging report also singled out five FBI employees who were involved in the Clinton investigation — including FBI agent Peter Strzok and former FBI lawyer Lisa Page — for messages that the report said expressed political bias against then-candidate Donald Trump.

But while the inspector general’s office referred the five employees back to the FBI to judge whether they violated the bureau’s internal code of conduct, it also wrote that it found no evidence to suggest that their political biases influenced any of the FBI’s investigative decisions during the Clinton probe.

Horowitz is also scheduled to testify before the House Judiciary and Oversight Committees, which are holding a joint hearing about the report Tuesday.
