WATCH LIVE: DOJ Inspector General, FBI Director Testify Monday About IG Report

Justice Department Inspector General Michael Horowitz and FBI Director Christopher Wray will head to Capitol Hill Monday for an expected grilling from senators about the inspector general's scathing report on the FBI's mishandling of the Hillary Clinton email investigation in 2016.

The nearly 600-page report, which was more than a year in the making, provided ample political ammunition to lawmakers on both sides of the aisle when it was released Thursday.

President Trump claims the report "totally exonerates" him in the Russia investigation into possible coordination between his campaign and Moscow during the 2016 election. But the IG report does not examine the Russia probe; it focuses solely on the investigation into Hillary Clinton's private email server.

In the report, the inspector general did conclude that former FBI director James Comey made a series of mistakes, including a "serious error of judgement" in announcing the reopening of the Clinton investigation less than two weeks before Election Day in 2016. As Trump and his allies work to discredit Comey and others who either are or were previously involved in investigating his campaign, the report offers a potential way to undermine them.

Democrats, on the other hand, can point to Horowitz's findings that no decisions made by the Justice Department while investigating Clinton's private email server "were affected by bias or other improper considerations," despite Trump's consistent accusations of a "deep state" conspiracy against him, and in favor of Clinton.

Monday's hearing before the Senate Judiciary Committee will begin at 2 p.m. ET.

Both Wray and Horowitz last testified before the committee in July. Wray answered questions from senators when he was nominated by President Trump to lead the FBI, and Horowitz spoke about enforcement of the Foreign Agents Registration Act.
