Actress Debra Messing on Saturday promoted a sign posted outside of an Alabama church that called African-Americans supporting President Trump a “mental illness.”

“THANK YOU #Alabama,” Messing wrote in response to a sign that reads, “A black vote for Trump is mental illness.”

“A white vote for Trump is pure racism,” the sign states on the other side.

The 51-year-old also called for the doxxing of Hollywood’s Trump supporters.

Messing joined her “Will & Grace” co-star Eric McCormack in calling for journalists to publish a list of attendees at a Beverly Hills fundraiser for the president.

“Hey, @THR, kindly report on everyone attending this event, so the rest of us can be clear about who we don’t wanna work with. Thx,” McCormack said.

“Please print a list of all attendees please. The public has a right to know,” Messing also tweeted.
