Trump mindlessly tweets out link to anti-Muslim website shortly after New Zealand mosque shooting

President Donald Trump tweeted out a link to the anti-Muslim Breitbart News website shortly after news broke about a massacre at a New Zealand mosque.

The shooting, which left 49 people dead, was live-streamed on Facebook, and the gunman apparently posted a manifesto on the far-right-friendly 8chan forum and set up other social media accounts to promote the screed ahead of the massacre.

Late Thursday, after the shooting had been reported by U.S. media and presumably after the president would have been briefed, Trump tweeted out a link to the Breitbart homepage, where the lead story at that point was an article highlighting disgraced New York City police commissioner Bernard Kerik's claims about special counsel Robert Mueller.

Trump's tweet offered no commentary on the link to Breitbart's homepage, which frequently features inflammatory content about Islam and Muslims, and the right-wing site soon changed its lead story to the Christchurch shooting.

Other social media users were appalled and confused.
