An anti-Muslim organization had planned to host its annual gala next month at Mar-a-Lago, President Trump’s private club in Palm Beach, Fla., before an apparent reversal on Sunday, a day after news reports appeared about the event.

The group, ACT for America, claims to be the nation’s largest grass-roots national security organization, and is considered the largest anti-Muslim group in the United States, according to the Anti-Defamation League and the Southern Poverty Law Center, which tracks such groups.

Michelle Malkin, a conservative columnist, author and television commentator, had been the planned keynote speaker, according to an invitation that was posted on the organization’s website.

On Sunday, the invitation was removed from the website and a spokeswoman for the Trump Organization said in an email, without elaboration, “This event will absolutely not be taking place at Mar-a-Lago.”
