On Tuesday, the Republican Party of New York and Great America Alliance announced that the duo will be in the nation’s capital to headline a show on Thursday, Jan. 19 at an inaugural-week gala, according to the Washington Examiner.

Rich was also on season 11 of NBC’s “The Celebrity Apprentice” when Trump was the host. He won that season.

The gala takes place the night before the inauguration. It is unknown whether or not the president-elect plans to attend the event.

According to the report, former mayor of New York City Rudy Guiliani and actor Jon Voight are expected to appear at the gala.

“We are proud to have been a part of this extraordinary movement and excited to be partnering with Republican Party in the president-elect’s home state of New York,” Eric Beach, co-chairman of Great America Alliance said in a statement. “We look forward to celebrating with the many people that contributed to his historic victory.”

The Radio City Hall Rockettes and the Mormon Tabernacle Choir are scheduled to perform at the actual inauguration.

Andrea Bocelli recently backed out of performing at the ceremony amid backlash from his fans. Country singer Garth Brooks has also declined to perform over negative pressure from fans, another report claims.

“They both bowed to the pressure,” one source said. “Their phones were blowing up, and they decided it just wasn’t worth it.”
