Story highlights But a city official said that Trump's head of security asked for such a meeting

"He wanted to exploit the department and have a press conference with cops," the official said

(CNN) Donald Trump's campaign is denying that the candidate wanted to meet with New York police officers Friday afternoon and hold a press conference at a midtown precinct in a show of support following the Dallas police ambush.

"Mr. Trump and the campaign did not reach out with a request to address a roll call," said campaign spokeswoman Hope Hicks, referring to the mid-afternoon shift change of officers.

But a city official said that Keith Schiller -- Trump's head of security -- called a community affairs officer at the precinct asking for such a meeting. The officer ran the request up the chain of command at the New York Police Department, and it was quickly denied, the official told CNN.

"He wanted to exploit the department and have a press conference with cops," the official said.
