Several celebrities took to social media late Friday and slammed President Donald Trump for pardoning Sheriff Joe Arpaio, who was convicted in July of violating a federal court order not to detain suspected illegal immigrants.

Actor and director Rob Reiner, a very vocal Trump critic, called the president a “truly hateful human being” who will go down in history as a “racist president”:

DT, not to be upstaged by an act of God,announces future ban of transgenders from military & pardons Arpaio. DT-a truly hateful human being. — Rob Reiner (@robreiner) August 26, 2017

With the pardoning of Joe Arpaio, Donald Trump has solidified his place in U.S. history. America knowingly elected a racist president. — Rob Reiner (@robreiner) August 26, 2017

Elsewhere, House of Cards creator Beau Willimon slammed Trump for his policy barring transgender people from the U.S. armed forces and for pardoning the Arizona sheriff. “@realDonaldTrump is a hateful, cowardly menace,” Willimon wrote to his 141,000 Twitter followers:

Left-wing comedian Sarah Silverman said, “Trump’s pardon of Arpaio was just 1 more in a series of secret handshakes w the white power movement,” while Hollywood mega-producer Judd Apatow used the president’s pardon to urge his followers to register to vote:
