Former President Donald Trump attended the wake of slain NYPD officer Jonathan Diller on Thursday afternoon at a Massapequa Park funeral home, while calling for law and order, Fox News reports.

"Such a sad, sad event. Such a horrible thing. And it's happening all too often and we're just not going to let it happen," Trump said.

"We need law and order," he added. 

Diller was fatally shot on Monday during a contact in Queens after a man with 21 prior arrests allegedly shot him in the stomach as Diller was trying to get the suspect, Guy Rivera, 34, to exit a vehicle. Rivera opened fire on Diller and his partner at about 5:45 p.m. Monday. The officers approached the vehicle because it was illegally parked at a bus stop. 

The Trump campaign first announced Wednesday that the 45th president would attend the wake. New York City Mayor Eric Adams was anticipated to also attend the wake following Trump. 

Trump told the New York Post in a recent interview that the "radical lunatic left" is ruining cities and preventing police officers from doing their jobs.
