U.S. Attorney General Eric Holder is under investigation.
He's been accused of lying under oath while testifying about the Justice Department's crackdown on leaks to reporters.
The House Judiciary Committee is conducting the investigation.
Earlier this month, Holder denied involvement in the government's controversial seizure of associated press phone records.
But a statement from the Justice Department reveals the AG was involved in a similar case involving a FOX reporter.
If lawmakers determine Holder committed perjury he could face jail time. That's not likely, but there are calls for him to step down.
