Trump sparked criticism from Britain's highest officials Wednesday

Washington (CNN) President Donald Trump's decision to retweet anti-Muslim content from a leader of a far-right British political group elevated the conversation, White House press secretary Sarah Sanders said Thursday, admitting that Trump likely didn't know the content came from an ultra-nationalist political group.

Trump had sparked criticism from Britain's highest officials Wednesday when he retweeted three anti-Muslim messages from Jayda Fransen, the deputy leader of the group, Britain First. Trump's support for the messages, which contained videos depicting purported Muslims assaulting people and smashing a statue of the Virgin Mary, drew condemnation from England, including from Prime Minister Theresa May.
