Foreign leaders have made no secret of their disdain for Donald Trump — and now French President Francois Hollande has made it explicit, endorsing Hillary Clinton for the White House.

"The best thing the Democrats can do is to get Hillary Clinton elected," Hollande wrote in a column for a French newspaper, according to a translation by Politico.

Trump, meanwhile, offers slogans that are "barely different from the extreme right in Europe and in France," and electing him “would complicate relations between Europe and the U.S.," Hollande wrote.

It is unusual for a foreign leader to make such an explicit endorsement in a U.S. presidential election.
