The US Secret Service has confirmed it is investigating accusations of sexual assault against one of its agents, reportedly with the alleged victim being a female staff member of Kamala Harris’s election campaign team.

The federal agency, already under fire over operational lapses that preceded the attempted assassination of Donald Trump in July, confirmed to NBC News on Wednesday: “The employee has been placed on administrative leave pending the outcome of the investigation.”

According to RealClearPolitics, the agent allegedly forced himself on to the woman and groped her in her hotel room after eating a meal and drinking alcohol with her and several other Harris campaign staffers in a restaurant in Green Bay, Wisconsin.
