The son of Republican Senator Rand Paul says he will seek treatment for a drinking problem after he went on an anti-Semitic tirade to Republican Congressman Mike Lawler.

Tuesday night at the Capitol Hill dive bar, the Tune Inn, William Paul confronted Lawler over an upcoming House primary in Paul's home state of Kentucky. 

Paul told Lawler that if libertarian-leaning Republican Representative Thomas Massie loses his primary last week it's thanks to 'your people,' NOTUS first reported. 

'My people?' Lawler asked Paul.  

'Yeah, you Jews,' the senator's son responded. 

'Do you think I'm Jewish?' Lawler asked. 'I'm not.' 

In his own telling to reporters on Capitol Hill Wednesday, Lawler noted how he told Paul he was an 'Irish-Italian Catholic.' 

'Oh wow, I'm so sorry for calling you a Jew,' Paul then said, according to NOTUS. 

But the exchange didn't end there. 

Lawler said Paul engaged in a 'roughly 10 minute diatribe' in which the senator's son used a number of anti-Semitic tropes.  

'And at one point, you know, [he] said he hates Jews and hates gays and doesn't care if they die, and I think that's f***ing disgusting,' the New York Republican told reporters outside the Capitol Building. 

Lawler said the conversation 'shortly thereafter' ended, with Paul making a dramatic exit. 

NOTUS reported that on his way out, the Senator's son 'knocked his barstool down and tripped over it.' 

'He gave me the middle finger and then tripped on his way out the door,' the congressman described. 

The whole exchanged happened in front of Reese Gorman, a Congressional reporter for NOTUS. 

After the story broke and after Lawler confirmed the account to reporters, Paul put up a public apology on his X account.

His handle is TastyBrew1776. 

'Last night, I had too much to drink and said some things that don't represent who I really am,' Paul said. 'I'm sorry and today I am seeking help for my drinking problem,' he said. 

Paul had worked on the Hill for Representative Mike Collins, now a US Senate candidate in Georgia, whose office was previously rocked by a scandal involving a chief of staff hiring his girlfriend. 

Senator Paul's office did not immediately respond to the Daily Mail's request for comment. 

Paul, who is now in his 30s, racked up a number of alcohol-related charges in his youth, according to reports from the Louisville, Kentucky-based WDRB. 

In 2015, he was pulled over in Lexington, Kentucky and cited for driving under the influence of alcohol and pleaded guilty.  

At the time, his father was readying a presidential bid. 

In 2013, Paul was charged with underage drinking, disorderly conduct and simple assault against a female flight attendant. 

Those charges were later dropped. 

Also that year, Paul was cited for being a minor in possession of alcohol at the Keeneland Race Course.
