The six-year criminal investigation focused on DeLay's ties to imprisoned former lobbyist Jack Abramoff.
One of DeLay's lawyers, Richard Cullen, said Monday the Justice Department's Office of Public Integrity informed DeLay's legal team early last week that it was ending the investigation. The Justice Department has not publicly commented on whether the investigation has ended.
DeLay, a Republican from Texas, is a former House majority leader.
