The Police Department is seeking to revoke former President Donald J. Trump’s license to carry a concealed weapon after his conviction in his New York hush-money case, according to two people with knowledge of the matter.

Mr. Trump had a concealed carry permit in New York and had three pistols registered under the permit, the people said. Two of them were turned over to the Police Department’s License Division around the time Mr. Trump was charged in April 2023 with 34 counts of falsifying business records, according to the people with knowledge of the matter. The third pistol had already been legally transferred to Florida. It is unclear whether it is still in Mr. Trump’s possession.

Under federal law and state law in New York and Florida, people with felony convictions are barred from possessing a firearm.

The Police Department will complete an investigation that is likely to lead to the revocation of Mr. Trump’s concealed carry permit, according to the people with knowledge of the matter. Mr. Trump has the right to file a challenge to the move.

The department’s actions were first reported by CNN.

In a statement, Steven Cheung, a spokesman for Mr. Trump’s campaign, did not directly address the possibility of Mr. Trump’s permit being revoked, saying, “Biden’s cronies in the Democrat Party are panicked and have chosen to continue to abuse our once great justice system to pursue their number one political opponent and interfere in the coming election.”

The Police Department did not immediately respond to a request for comment.
