NEW YORK (AP) โ€” Federal agents on Tuesday raided the offices of a New York City police union, the Sergeants Benevolent Association, and the Long Island home of its bombastic leader, who has clashed repeatedly with city officials over his incendiary tweets and hard-line tactics.

An FBI spokesperson said agents were โ€œcarrying out a law enforcement action in connection with an ongoing investigation.โ€ The spokesperson said he could not give details of the investigation.

Along with the unionโ€™s Manhattan headquarters, agents also searched union president Ed Mullinsโ€™ home in Port Washington, Long Island.

Messages seeking comment were left with Mullins and the union.

Mullins, who is also a police sergeant, is in the middle of department disciplinary proceedings for tweeting NYPD paperwork last year pertaining to the arrest of Mayor Bill de Blasioโ€™s daughter during protests over the Minneapolis police killing of George Floyd.

Mullins is also suing the department, claiming they were trying to muzzle him by grilling him and recommending disciplinary action over his online missives.

Mullinsโ€™ department trial for the alleged paperwork breach began last month but was postponed indefinitely after one of his lawyers suffered a medical emergency.

Mullinsโ€™ lawyer denies he violated department guidelines, arguing paperwork with Chiara de Blasioโ€™s personal identifying information, such as her date of birth and address, was already posted online.

Asked about the raid Tuesday, Mayor de Blasio told reporters he didnโ€™t have enough information to comment.

โ€œI think heโ€™s been a divisive voice,โ€ de Blasio said of Mullins. โ€œBut that doesnโ€™t cause me to feel anything in this situation because I donโ€™t know whatโ€™s happening. All I hear is an FBI raid. I donโ€™t know the specifics, I donโ€™t know who itโ€™s directed at. I want to really hear the details before I comment further.โ€

The Sergeants Benevolent Association represents about 13,000 active and retired New York police sergeants, a rank above police officer and detective but below captain and lieutenant.

Under Mullinsโ€™ nearly two decades of leadership, the union has fought for better pay โ€” with contracts resulting in pay increases of 40% โ€” and staked a prominent position in the anti-reform movement.

Along with Mullinsโ€™ periodic appearances on cable networks like Fox News and Newsmax โ€” including one in which he was pictured in front of a QAnon mug โ€” perhaps the unionโ€™s most powerful megaphone is its 45,000-follower Twitter account, which Mullins runs himself, often to fiery effect.

In 2018, amid a rash of incidents in which police officers were doused with water, Mullins suggested it was time for then-Commissioner James Oโ€™Neill and Chief of Department Terence Monahan to โ€œconsider another professionโ€ and tweeted that โ€œOโ€™KNEEL must go!โ€

Oโ€™Neill retorted that Mullins was โ€œa bit of a keyboard gangsterโ€ who seldom showed up to department functions.

Last year, Mullins came under fire for tweets calling the cityโ€™s former Health Commissioner, Dr. Oxiris Barbot, a โ€œbitchโ€ and U.S. Rep. Ritchie Torres a โ€œfirst-class whore.โ€

Mullins was upset over reports Barbot refused to give face masks to police in the early days of the pandemic and angry with Torresโ€™ calls for an investigation into a potential police work slowdown in September 2020.

Torres, who is gay, denounced Mullinsโ€™ tweet as homophobic.

On Tuesday, Torres referenced that tweet in reacting to the news of the raid, writing: โ€œEd Mullins, who famously called me a โ€˜first-class whoreโ€™ for daring to ask questions about the @SBANYPD, just got a first-class raid from the FBI.โ€

In 2019, it wasnโ€™t tweets that got Mullins in trouble, but rather comments he made in a radio interview suggesting that slain Barnard College student Tessa Majors had gone to the park where she was killed to buy marijuana. Police later arrested three teens, saying sheโ€™d been stabbed during an attempted robbery.

Majorsโ€™ family called Mullinsโ€™ remarks on the radio show โ€œdeeply inappropriateโ€ victim blaming and urged him โ€œnot to engage in such irresponsible public speculation.โ€
