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.

I am a New Zealander watching news coverage of a mass shooting at a mosque in Christchurch. The person who did this is a white supremacist who was probably influenced by the crap spewed by hate sites like Breitbart. YOU are part of the problem for the rise in hate crime. — Jen Longshaw (@JenLongshaw) March 15, 2019

You’re just out here plugging Breitbart for no reason whatsoever? Cool. That’s a totally normal, presidential thing to do. Especially in the midst of what’s happening in Christchurch. Which is a city in NZ by the way, not a place of worship where you inexplicably sign bibles. — Daddy Files (@DaddyFiles) March 15, 2019

What a predictably disgusting asshole you are. Our friends in Christchurch, New Zealand are reeling from a terror attack by a Radical White Terrorist, and AGAIN you say nothing. Instead, you post the fake news hate rag, Breitbart. YOU. ARE. FILTH. — BrooklynDad_Defiant! (@mmpadellan) March 15, 2019

you typed breitbart dot com into the wrong space mr president sir — raandy (@randygdub) March 15, 2019

Of course you posted this as news breaks that a far right lunatic shot up a Mosque. You know exactly what you’re doing. — Andrew Abramson ? (@AbramsonFL) March 15, 2019

No words of condolences?

No words of mourning?

No words of support?

No words of condemning the attack? Just a useless link to a conspiracy website that has been proven to push lies and right wing extremism. You make me sick. — Ida Skibenes ❄️ (@ida_skibenes) March 15, 2019

How about tweeting about the horrific mass-shooting at the #NewZealand mosques, and acting like a world leader instead of a world buffoon on Twitter. Shame on you… #Trump — Andy Ostroy (@AndyOstroy) March 15, 2019

You were too lazy and embarrassing to tweet a note of condolence to NZ PM #JacindaAdern. Instead you posted from a well-known Islamophobic site. Disgraceful. — Victoria Brownworth (@VABVOX) March 15, 2019

The third story down is… trump encouraging supporters to attack people wtf is going on — Floyd (@shaunep815) March 15, 2019

I think you misspelled Christchurch. — Rogue NASA (@RogueNASA) March 15, 2019

Yes you are correct, that is one if the websites that caused this tragedy. — Andrew Jon Thomson (@HelloAndrew) March 15, 2019

Apparently he was fresh out of thoughts and prayers. — John Hart (@farmgeek) March 15, 2019

The New Zealand Mosque shooter says in his manifesto that he admires Donald Trump because Trump is “a symbol of renewed white identity and common purpose.” — Christopher O’Riley (@cjoriley) March 15, 2019

Seriously disgraceful. — Wander Woman (@WanderWomanPhD) March 15, 2019
