As you may be aware, Duncan Hunter, (the son) of Duncan Lee Hunter, is under investigation for misuse of campaign funds.
What I did not know, until now, was that it is alleged that he spent his money on his girl(s) on the side:

Federal prosecutors alleged in a new court filing this week that Rep. Duncan D. Hunter used campaign funds to help facilitate extramarital affairs, and they want to show jurors evidence of the relationships at his upcoming trial.

The filing Monday alleges Hunter (R-Calif.) used campaign money to fund trips, dinners and drinks with women with whom he was romantically involved — three lobbyists, a woman who worked in his congressional office and another who worked for a member of House leadership.

In the new filing, prosecutors allege Hunter’s romantic entanglements blossomed as he used campaign money for large expenses — such as a ski trip near Lake Tahoe — and small ones, such as Uber rides to and from the women’s homes.

………

Hunter and his wife, Margaret, were charged last year with using more than $250,000 in campaign funds to pay for family vacations, theater tickets and other personal expenses. Prosecutors say he used his campaign account as his “personal piggy bank” to live well beyond his means.

………

Hunter’s wife, meanwhile, pleaded guilty in the case this month and agreed to “tell everything,” according to a copy of her agreement with prosecutors. Prosecutors revealed in another court filing they have texts between Margaret and her husband, who have three children, in which they discussed using campaign funds on personal expenses.

Ammar Campa-Najjar, a Democrat who is challenging Hunter in the next election, tweeted that Hunter was “literally in bed with lobbyists.”

(emphasis mine)

The kicker is that he won reelection last year, when he had already been charged.
