The FBI's investigation of U.S. Rep. Duncan Hunter (R-50th District) has widened, according to newly-released court documents.
A search warrant made public Wednesday reveals that federal agents searched the office of Hunter's campaign treasurer in Alexandria, Virginia.
The investigation now involves possible bank fraud, falsified reports and conspiracy.
The search warrant states that FBI agents were looking for campaign spending records and communications between Hunter, his wife, and their aides, as well as the Hunter family's travel records.
Hunter has been criticized for improper use of campaign funds, but has repeatedly said he repaid the questionable expenses.
During the search of the campaign treasurer's office, agents seized computers, external hard drives and computer spreadsheets with financial information.
The search happened February 23, but was first reported on Twitter Wednesday by Seamus Hughes, a researcher at George Washington University.

Marston referred questions to his attorney, Jason Torchinsky, who provided the following comment to NBC 7: "Both [Marston and Hunter] have cooperted fully with all government inquiries related to the Committee. Neither Election CFO nor any of its employees have reson to beleive that they are subjects of any investigation."
One of Hunter's re-election opponents, Josh Butner, said, "As this investigation drags on, Hunter has proven he is unable to focus on his constituents that need a leader in Washington."
