Under investigation by the Justice Department, former U.S. Rep. Curt Weldon has transferred all of his campaign money to a fund he established for his legal defense.

Weldon, a Republican who represented Delaware County for 10 terms, transferred roughly $80,000 over several months from the Weldon Victory Committee to the Weldon Legal Expense Trust, according to federal election records. Weldon closed the campaign fund May 22. Federal Election Commission rules allow campaign funds to be used for legal defense work if it is related to a person’s activities as a candidate or officeholder.

Philadelphia lawyer Jeffrey M. Lindy confirmed that he was trustee for the defense fund but declined to comment further. Weldon’s lawyer, William J. Winning, declined to comment. Weldon has denied wrongdoing and has predicted that he will be vindicated.
