President Donald Trump said on Tuesday that he was briefed on the Monday night mass shooting in New York City, saying his “heart was with” the four people killed. “I trust our Law Enforcement Agencies to get to the bottom of why this crazed lunatic committed such a senseless act of violence,” he wrote in a Truth Social post.

The Justice Department on Thursday announced a lawsuit against New York City’s so-called sanctuary city policies, days after the Trump administration blamed those policies for the shooting of an off-duty US Customs and Border Protection officer in Manhattan.

US President Donald Trump said a shooting that killed four people in a New York skyscraper was "a senseless act of violence." Police are investigating possible grievances the suspect, who also died, had against the NFL.
