Weller accepted money from two convicted associates of former congressman Duke Cunningham. Weller's spokesman said that the donations probably originated from his support of the research and development tax credit and the money was donated to a charity in Oregon. Weller and 11 other congressmen were subpoenaed to testify in the trial of Brent R. Wilkes, the contractor accused of bribing Cunningham. The subpoenas were withdrawn by defense attorneys on October 3, 2007 when it became apparent the trial judge would quash them anyway. Weller and the other 11 did not testify in the trial.
