President TrumpDonald John Trump2020 Democrats spar over socialism ahead of first debate Senate passes .5 billion border bill, setting up fight with House 'Teflon Don' avoids the scorn of the 'family values' GOP — again MORE drew a round of applause from law enforcement officials on Friday after he took a swipe at mayors who don't let police "do their job."

"I've met police that are great police that aren't allowed to do their job because they have a pathetic mayor or a mayor that doesn't know what's going on," Trump said in a speech in Long Island, N.Y., eliciting applause from a crowd of police officers standing behind him.

"Were you applauding for someone in particular?" Trump asked with a smile, shaking his head. The jab was interpreted by some as a veiled swipe at New York City Mayor Bill de BlasioBill de BlasioThe Hill's 12:30 Report: Anticipation high ahead of first debate Where 2020 Democrats stand in betting markets ahead of first debate Trump says he'll watch Democratic debate while en route to Japan 'because I have to' MORE.



De Blasio has had a particularly strained relationship with New York City Police officers, who have accused the mayor in the past of helping breed anti-police sentiment in the city.

The NYPD did not attend the event, which was not held within New York City boundaries. 

Trump's address to law enforcement on Friday focused on his administration's efforts to crack down on gang violence, particularly the MS-13 gang, which has a sizable presence in New York.

In the speech, the president harangued politicians, whom he accused of stymying police officers' ability to do their jobs. 

"They're there right now because of weak political leadership, weak leadership, weak policing and, in many cases because the police weren't allowed to do their job," Trump said, referring to MS-13.
