More than a dozen House members, including Michigan Reps. Pete Hoekstra and Joe Knollenberg, have been subpoenaed to testify in a bribery trial.
But all say they won't comply on the advice of House attorneys.
They're being called to testify in the trial of contractor Brent Wilkes, who is facing 25 counts of bribery, fraud, money laundering and conspiracy.
Congressman Randy "Duke" Cunningham pleaded guilty in 2005 to taking more than two million dollars in bribes from Wilkes and others.
A number of the subpoenaed lawmakers received campaign donations or other favors from Wilkes.
House lawyers are preparing to try to quash the subpoenas, after failing to get a clear explanation of why the testimony is necessary.
