Peter Strzok, the FBI agent who vowed to block President Trump from winning the White House, will be in the congressional hot seat Wednesday.

Strzok was subpoenaed Friday to tell the House Judiciary Committee about his actions as he led investigations into both Hillary Clinton and Donald Trump in the months before the 2016 election.

Strzok later lost a job on special counsel Robert Mueller’s staff when thousands of his text messages to his lover, FBI lawyer Lisa Page, revealed his loathing of Trump and support for Clinton.

He was escorted out of FBI headquarters on June 15 after the Department of Justice revealed a previously suppressed text in which Strzok, contemplating a Trump victory, wrote, “We’ll stop it.”
