Donald Trump, Jr. will also be speaking at the event that will take place Feb.1, the day before Super Bowl Sunday.
“Roseanne is is a really loyal Trump supporter,” Trumpettes founder Toni Holt Kramer told the paper.
“If there was ever anybody who really put their mouth on the line and said how much she loves the president, she is one of them. You can’t get a hotter name in town.”
According to Kramer, tickets to the third annual event were already sold out before it was announced that Barr would be speaking.
