House Judiciary Committee Chairman Bob Goodlatte (R-Va.) issued a subpoena for FBI agent Peter Strzok on Friday.

The date of his deposition is expected to be Wednesday, June 27, and may also include the House Oversight Committee.

Why the subpoena?

While Strzok's attorney reported days ago that the embroiled FBI employee would be willing to testify voluntarily in hopes of clearing his name, the Judiciary Committee issued the order so that they could nail down a specific date for the agent to appear.

The attorney representing Strzok, Aitan Goelman said in a statement on Friday: "We regret that the Committee felt it necessary to issue a subpoena when we repeatedly informed them that Pete was willing to testify voluntarily."

What's this about?

Strzok had an integral role in leading the FBI's investigation into Hillary Clinton's email scandal, and was also part of special counsel Robert Mueller's team investigating allegations of Russian collusion surrounding the Trump campaign.

But text messages between Strzok and fellow FBI employee Lisa Page — with whom he is romantically linked — have raised questions about political bias within the FBI.

After the texts were publicly exposed, Strzok was removed from the investigation to another position within the FBI. He was escorted from the FBI building earlier this week, amid the Bureau's internal review of his conduct.
