FBI agent Strzok sent text messages to then-FBI attorney Lisa Page criticizing President Trump's 2016 candidacy. Inspector General Michael Horowitz revealed in a report released Thursday that multiple agents, including Strzok, had messaged each either supporting Clinton or opposing Trump. Strzok worked on the FBI's investigation into Clinton's use of a private email server.

In one message, Strzok said "we'll stop" Trump from becoming president. 

"He told his girlfriend that he was going to make sure that he could,” McCarthy added. “This is the inside of the FBI, the highest levels, and those in charge of an investigation that should end after the millions of dollars they have already spent.”

The IG report also concluded that no political bias directly affected the FBI's investigation into Clinton. 

Strzok, who was initially a part of Mueller's team in his investigation into Russian meddling in the 2016 election and possible collusion with the Trump campaign, was dismissed in July after an internal probe. Page was dismissed as well that same summer. 

Trump and GOP lawmakers are pointing to the text messages as a display of systemic political bias against him in the Mueller investigation.
