After an altercation on Tuesday with a congressman during which he made repeated antisemitic comments, Sen. Rand Paul’s son William apologized and said Wednesday he is “seeking help” for his drinking problem.

“Last night, I had too much to drink and said some things that don’t represent who I really am,” William Paul tweeted on Wednesday afternoon. “I’m sorry, and today I am seeking help for my drinking problem.”

The incident between Paul and Rep. Mike Lawler, a New York Republican, occurred late Tuesday at the Tune Inn bar and restaurant in Washington, DC, in front of NOTUS reporter Reese Gorman, who reported first-hand about the incident.

Paul approached Lawler and he said if Kentucky incumbent Rep. Thomas Massie loses his primary on May 19, it will be because of “your people,” NOTUS reported.

Lawler, who is not Jewish, clarified that he is Irish, Italian, and Catholic, according to Gorman’s account.

“And he goes, ‘Oh! Oh, I’m sorry to accuse you of that,’” Lawler recalled during a press availability tweeted by a reporter from CourthouseNews. “Which is just a remarkable statement in and of itself. But he then went on a roughly 10-minute diatribe about Israel, about Jews, about Paul Singer, and accusing Jews of being responsible for so many things, playing right into the typical antisemitic tropes that so many people rely on.”

A TV spot for Massie that began running this week targeted hedge fund billionaire Paul Singer with a Pride flag-patterned Star of David placed next to Singer’s head. The ad called Singer a “major pro-gay, pro-trans activist who works with far-left, hardcore Democrats.”

Singer, who is Jewish, is a Republican and a major donor to Republican candidates. His son is gay, and he is a longtime supporter of gay rights.

William Paul’s father Rand, is Kentucky’s junior senator. A Republican who has run for president, Rand Paul, announced his endorsement of Massie in October.

“At one point, he said that he hates Jews and hates gays and doesn’t care if they die,” Lawler recalled about his encounter with William Paul in the interview. “And I think that’s f***ing disgusting. So, you know, the conversation shortly thereafter ended, he gave me the middle finger, and then tripped on his way out the door.”

Lawler is the representative for New York’s 17th district, a swing district that includes a significant Orthodox Jewish population in Rockland County.

The Kentucky Jewish Council, which advocates against antisemitism in the state, issued a statement denouncing the incident.

“We are deeply disturbed both by the antisemitic conspiracy theories posited by Mr Paul and with his comfort in harassing someone he thought was Jewish in a public place,” the group said. “We regret that Congressman Lawler had to experience the kind of abuse far too many American Jews suffer on a regular basis.”

Tuesday night’s altercation between Paul and Lawler was not the first time in recent months that a public figure who is not Jewish was the target of an antisemitic attack. In March, following the attempted car ramming on a synagogue and Jewish preschool in Michigan, Oakland County Sheriff Mike Bouchard, who is not Jewish, said he had been the target of antisemitic memes and insults.
