Will & Grace stars Eric McCormack and Debra Messing backtracked on their call to out and blacklist President Trump's supporters in Hollywood on Tuesday.

Trump plans to attend a Beverly Hills fundraiser in a couple of weeks during a trip to California. McCormack advocated on Twitter for the Hollywood Reporter to "kindly report on everyone attending this event, so the rest of us can be clear about who we don’t wanna work with."

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. https://t.co/7W3xPG3bI2 — Eric McCormack (@EricMcCormack) August 30, 2019

Messing reiterated McCormack's call to out those who attend the event hours later, but they have both received backlash since then. Many accused them of mirroring the late Sen. Joseph McCarthy, who attempted to oust communists from American influence, which led to a Hollywood blacklist of those who appeared disloyal to the United States.

"I want to be clear about my social media post from last week, which has been misinterpreted in a very upsetting way. I absolutely do not support blacklists or discrimination of any kind, as anyone who knows me would attest," McCormack's statement began.

"I’d simply like to understand where Trump’s major donations are coming from, which is a matter of public record. I am holding myself responsible for making educated and informed decisions that I can morally and ethically stand by and to do that, transparency is essential," it concluded.

Following McCormack's apology, Messing tweeted that she agreed with his message and added that his statement "perfectly explains the intent behind each of our posts concerning the fundraiser. I am posting it here because, honestly, I couldn’t have said it better."

The fundraiser on Sept. 17, which costs $1,000 per ticket, will take place the week of the Emmy Awards. The event is being hosted by Republican National Committee Chairwoman Ronna McDaniels, RNC Co-chairman Tommy Hicks Jr., Trump 2020 campaign manager Brad Parscale, and Trump Victory finance Chairman Todd Ricketts.
