Trump shooting updates: Shooter flew drone 200 yards from site hours before shooting

Security is being increased across New York City following a possible assassination attempt on former President Donald Trump, officials said.

Out of an abundance of caution, the NYPD is increasing its presence across the city, including at Trump Tower, 40 Wall Street, Foley Square and City Hall.

There is no threat or connection to New York City at this time.

"Whatever your politics, we should all be able to agree that violence is wrong and we should be able to disagree peacefully," Mayor Eric Adams said in a statement.

The Biden campaign said it will halt all ads for the presidential race.

"The Biden campaign is pausing all outbound communications and working to pull down our television ads as quickly as possible," a campaign spokesman said.

The White House announced that Biden will shortly deliver remarks with regards to the shooting at the Trump rally in Pennsylvania.

Former President Trump is getting treatment at a local medical facility and is doing OK, a law enforcement source told ABC News.

This will be “investigated as an assassination attempt until it is not,” according to the source.
