The Anne Frank Center for Mutual Respect has asked Twitter to suspend President Trump's Twitter accounts, accusing him of being "an accomplice to domestic terrorism."

"Dear @Twitter corporate: He is an accomplice to domestic terrorism. If you can't end @POTUS account, at least end @realDonaldTrump account," the organization wrote Tuesday, referring to the president's official and personal Twitter accounts.

Trump denounced specific white nationalist groups in a televised statement on Monday, two days after a car plowed through a group of counter-protesters in Charlottesville, Va., killing 32-year-old Heather Heyer.

"Racism is evil and those who cause violence in its names are criminals and thugs, including the KKK, neo-Nazis, white supremacists and other hate groups that are repugnant to everything we hold dear as Americans," the president said.

Trump faced pressure from Republicans and Democrats for not specifically condemning the groups earlier. Several lawmakers referred to the car attack as "domestic terrorism."

Trump again caused controversy Tuesday when he retweeted an image of a train hitting a CNN reporter.

"This is the violent image of the murder of a @CNN reporter @POTUS tweeted today, one day after his #FakeCondemnation of White Supremacy," the Anne Frank Center tweeted before asking Twitter to suspend Trump's accounts.

Trump has since deleted the retweet.

The organization has been a frequent critic of Trump and his policies throughout Trump's short tenure as president.

Its connections to Anne Frank's family were disputed in an April report.
