"To the dude who said I don't belong in America, I started a fundraising page for Syrian Refugees in your name," Penn said.
The funds raised would go to International Rescue Committee.
"We are better than the hateful people who tell us we don't belong in our own country, that America can't be a beacon of freedom and hope for refugees from around the world. We will turn their bigotry, along with the President's, into love," the home page of the fund-raising campaign reads.
On Sunday Penn thanked the donors. "This is such a testament to how proud we are of our beautiful country and how fired up we are to #resist our new President's dangerous policies with solidarity and love.
