“The criminal investigation into Rep. Duncan Hunter (R-CA) is intensifying as a grand jury in San Diego questions multiple former aides about whether the California Republican improperly diverted political funds for personal use,” Politico reports.

“Federal prosecutors have subpoenaed Hunter’s parents, as well as a female lobbyist with whom many people close to the congressman believe he had a romantic relationship.”

“The Justice Department is trying to determine whether hundreds of thousands of dollars from Hunter’s campaign account were spent improperly on his family and friends. Hunter already sold his home to pay back what even he now acknowledges were improper charges, moving his wife and kids in with his parents while he mostly lives in his Capitol Hill office.”
