Celebrities attacked President Donald Trump and demanded that gun laws be changed after the mass shooting in Las Vegas Sunday night that left more than 50 people dead and hundreds more injured.

Lady Gaga said prayers are nice, but “blood is on the hands of those who have the power to legislate,” as she mentioned Speaker Paul Ryan and Trump specifically in her tweet, after Stephen Paddock opened fire on the concert goers at the Route 91 Harvest Music Festival. In a second post, she called for Republicans and Democrats to work together for “gun control.” (RELATED: Michael Moore, Other Celebs Blame Trump For Charlottesville Riots)

This is terrorism plain and simple. Terror bares no race, gender or religion. Democrats & Republicans please unite now #guncontrol — xoxo, Gaga (@ladygaga) October 2, 2017

Victoria’s Secret model Gigi Hadid questioned whether the Second Amendment was worth it after the mass shooting.

“It sickens me the ease in which a TERRORIST can be sold a GUN. Is the ease really worth all these lives ?! This needs to stop,” Hadid tweeted.

House GOP could pass legislation this week to:

1. repeal restrictions on gun silencers

2. allow concealed carry across state lines — Emmy Rossum (@emmyrossum) October 2, 2017

This is heartbreaking! When will people understand that guns kill and make them harder to obtain. You cannot argue this fact anymore. Tragic https://t.co/N3BGAQIwNC — Karen Elson (@KarenElson_) October 2, 2017
