SAN DIEGO -- Defense contractor Brent Wilkes, an alleged co-conspirator in the federal bribery case against former Congressman Randy "Duke" Cunningham, is already in trouble with the U.S. District Attorney's Office in San Diego. But now, the state of Texas is investigating him.

The U.S. Attorney's Office said Wilkes gave or arranged hundreds of thousands of dollars worth of gifts, cash and favors for Cunningham.

Now, the district attorney in Austin, Texas, is asking for records relating to contributions made by Wilkes, his vice president Max Gelwix and related companies.

Those donations allegedly went to two political action committees founded by former U.S. House Majority Leader Tom Delay, who is also under investigation, 10News reported.

Meanwhile, Republicans on Capitol Hill are taking a hard look at Cunningham's situation and want to make changes.

Lee Terry, a Republican representative from Nebraska, and fellow Republicans are proposing the Public Trust and Accountability Act, which would strip any federal employee of their pension if they commit a white-collar crime.

As it stands, Cunningham is allowed to keep his pension, despite the bribery plea.

No one associated with the subpoenas returned 10News' calls for comment.
