The editor-in-chief of BuzzFeed sent a memo to employees that explained how to write about presidential candidate Donald Trump on social media.

According to Business Insider:

Smith noted that, while employees should avoid being "political partisans on social media," they shouldn't mince words about Donald Trump. 

In the memo, Smith wrote that because Trump is "out there saying things that are false and running an overtly anti-Muslim campaign," that it's OK to talk about Trump in a way that is similarly unfiltered.

"It is, for instance, entirely fair to call him a mendacious racist," Smith wrote, saying the news team's reporting is "rooted in facts, not opinion; these are facts."

Smith tweeted out his memo for everyone to see.
