The man accused of stealing money from Lt. Gov. David Dewhurst’s campaign coffers is now being investigated at the federal level. 

The Dallas Morning News reports Dewhurst campaign manager Kenneth “Buddy” Barfield is accused of taking at least $1 million from Dewhurst’s U.S. Senate campaign. Barfield is already accused of stealing at least $600,000 from Dewhurst’s state campaign committee.

The Dewhurst campaign first notified Travis County officials that something was wrong back in December, when an accountant noticed discrepancies in bank statements. A spokesman for Dewhurst told the Morning News that the investigation into the Senate account began not long after.

Signs of the alleged embezzlement showed up in campaign finance reports last month, when the Dewhurst campaign reported $3.3 million raised in the last reporting period. However, just $1.97 million in cash on hand was reported.
