Roseanne Barr isn’t pleased with Rob Reiner’s focus on the connection between Russia and the Trump administration, and she apparently isn’t afraid to let him know.

The Trump-supporting “Roseanne” star took to Twitter on Thursday to describe a run-in that she says she recently had with the liberal “All in the Family” alum over his involvement with the Committee to Investigate Russia, a website investigating whether Russia meddled in the 2016 presidential election to help Trump win.

“I drank too much in NYC and saw Rob Reiner and could not help myself — I went over to him & got into a fight with him over all that Russian BS,” Barr tweeted.

“I said, ‘You’re buying fake news,'” she continued. “He said, ‘I’m not going to listen to this. I’m out of here.’ I said — ‘u should politely discuss opinions!'”

Reiner, who is vocal about his opposition to Trump, is on the advisory board of Committee to Investigate Russia and has donated at least $100,000 to the cause. Barr’s tweets are below.
