Michael Moore has found a new Charlton Heston.

The documentary filmmaker visited Trump Tower in midtown Manhattan on Wednesday, armed with a placard that read, “We Are All Muslim.” Police asked the Oscar-winning director to leave, which he eventually did.

Moore, whose documentary Where To Invade Next opens on Feb. 12, was responding to the presidential candidate’s recent proposal to ban all Muslims from entering the country in light of the terrorist shooting in San Bernardino, California. Critics have ripped Trump for suggesting a policy so antithetical to American ideals — as well as one that could violate the Constitution — but polls indicate it has strong public support with Republican voters.

After visiting Trump Tower, Moore wrote an extensive “Dear Donald” Facebook post, criticizing Trump’s stance and sharing an unflattering portrait of the candidate from when both men appeared on a 1998 talk show together.

“Just before going on, I was pulled aside by a producer from the show who said that you were ‘nervous’ about being on the set with me,” Moore wrote. “She said you didn’t want to be ‘ripped apart’ and you wanted to be reassured I wouldn’t ‘go after you.’ … And so, as you may remember … I went up and introduced myself to you. …You seemed relieved, then leaned in and said to me, ‘I just didn’t want any trouble out there and I just wanted to make sure that, you know, you and I got along. That you weren’t going to pick on me for something ridiculous.’ … I was struck by how you, a self-described tough guy from Queens, seemed like such a fraidey-cat. You and I went on to do the show. Nothing untoward happened between us. I didn’t pull on your hair, didn’t put gum on your seat. ‘What a wuss,’ was all I remember thinking as I left the set.”

Moore expanded on his protest placard, writing, “I was raised to believe that we are all each other’s brother and sister, regardless of race, creed or color. That means if you want to ban Muslims, you are first going to have to ban me. And everyone else. We are all Muslim. Just as we are all Mexican, we are all Catholic and Jewish and white and black and every shade in between. We are all children of God (or nature or whatever you believe in), part of the human family, and nothing you say or do can change that fact one iota.”

The Trump campaign did not immediately respond to EW’s request for comment, and the candidate has not tweeted about Moore or the incident at Trump Tower.
