Hundreds are expected to pay their respects to slain NYPD officer Jonathan Diller on Long Island Thursday.

Visitation for family and friends is being held at the Massapequa Funeral Home at 4980 Merrick Road between 2 to 4 p.m. and 7 to 9 p.m. Thursday, followed by the same schedule Friday.

Former President Donald Trump is set to attend the services Thursday.

“President Trump is moved by the invitation to join NYPD Officer Jonathan Diller’s family and colleagues as they deal with his senseless and tragic death,” Karoline Leavitt, the former commander-in-chief’s campaign spokesperson, said in a statement on Wednesday.
