The chairwoman of the Federal Elections Commission made clear in a statement Thursday that it’s illegal for a candidate to accept anything from foreign nationals during an election — a day after President Trump suggested he might accept dirt on an opponent from a foreign government.

FEC chair Ellen Weintraub on Thursday tweeted, “I would not have thought that I needed to say this” over an image of a written statement that made her position on the issue clear.

“Let me make something 100 percent clear to the American public and anyone running for public office: It is illegal for any person to solicit, accept, or receive anything of value from a foreign national in connection with a U.S. election,” Weintraub said in the statement.

“This is not a novel concept. Electoral intervention from foreign governments has been considered unacceptable since the beginnings of our nation,” she added.

In an interview that aired Wednesday night, Trump said he’d be willing to accept damaging information about his 2020 opponents, should a foreign power offer it.

“I think I’d want to hear it. There isn’t anything wrong with listening,” Trump told ABC News.

“It’s not an interference, they have information…If I thought there was something wrong, I’d go maybe to the FBI — if I thought there was something wrong,” Trump added.

“But when somebody comes up with oppo research, right, they come up with oppo research, ‘oh let’s call the FBI.’ The FBI doesn’t have enough agents to take care of it. When you go and talk, honestly, to congressman, they all do it, they always have, and that’s the way it is. It’s called oppo research,” he continued.
