Donald Trump Jr. sparked anger online after he used Tuesday’s fatal shooting at YouTube’s headquarters in San Bruno, California, as an excuse to bash liberals.

San Diego resident Nasim Aghdam, 39, allegedly shot several people with a handgun before killing herself on Tuesday afternoon. A motive for the shooting is still under investigation.

In the wake of the attack, President Donald Trump’s eldest son wrote this muddled message on Twitter:

You think there’s any chance whatsoever that a mass shooters hateful Instagram and YouTube channels would be pulled immediately if they were NRA members as opposed to liberal Vegan PETA activists? Asking for a few million friends in the @NRA — Donald Trump Jr. (@DonaldJTrumpJr) April 4, 2018

The post drew ire from fellow tweeters, who criticized Trump Jr. for politicizing the incident and for offering up comment when the full circumstances were still unknown:

Three people were just shot and the President's son is railing against Vegans on Twitter... — Breetbort (@Breetbort) April 4, 2018

What the hell is the matter with you. Calm down and think before you spout off on serious issuses.people are dead and wounded,it's not a game for you to have political fun with — Kevin Heldman (@kevinjayheldman) April 4, 2018

Doesn't matter that she identified in those ways. She used a gun to kill people. Gun violence kills 10k a year in this country. Unacceptable. — Danny Pharr (@dannypharr) April 4, 2018

Oh shut up, you idiot. This is your fourth or fifth tweet TONIGHT saying the exact same nonsense. Just remember this the next time you open your damn yap about LIBERALS politicizing shootings. — Daniel Fienberg (@d_fienberg) April 4, 2018

He's trying to stay meaningless from his Dad's lead on thoughts and prayers. — Inuyashian 🌊 (@TheCompWiz) April 4, 2018

Never seen anyone so excited about people getting shot! Sad! — Michael Coleman (@sacmike) April 4, 2018

"Asking for a [few million] friend[s]" is a sort of immature way to address a serious issue like mass shooting. I wouldn't expect anything else from you. Stay out of policy, it's not your thing, kind of like property management. — m_l_a_d_y (@m_l_a_d_y) April 4, 2018

Shabby statement. — Jason Dittmer (@jddittmer) April 4, 2018
