Trump often uses his Twitter account to make policy announcements or feud with his political foes, a habit that has often sparked backlash from his critics.

The president prompted international backlash in November after he retweeted several videos from a far-right anti-Muslim group called Britain First.

The leader of the group, whom Trump retweeted, was arrested for hate crimes in the U.K. and at least one of the videos was revealed to be a hoax.

White House press secretary Sarah Huckabee Sanders defended the retweets, saying "the threat is real" even if the videos weren't.

The retweets prompted a condemnation from U.K. Prime Minister Theresa May, who issued a statement through a spokesman calling Trump's actions "wrong."
