NEW YORK — In the days before President Donald Trump’s administration moved to drop Mayor Eric Adams’ corruption indictment, federal authorities raided the upstate New York home of Dwayne Montgomery, a former New York City Police Department inspector friendly with Adams, as part of an expanding investigation into alleged crimes linked to Adams and his campaigns, according to bombshell new records released Friday.

The Jan. 23 raid at Montgomery’s Middletown home was part of a flurry of previously unknown law enforcement actions detailed in a trove of 1,785 pages of search warrants and other materials from the yearslong federal corruption probe into Adams.

The materials provide a glimpse into what prosecutors may have laid out had Adams’ case gone to trial. In addition to the revelations about Montgomery and the feds’ suspicion about another straw donor scheme, the documents reveal FBI agents accused Adams of lying about one of his personal cellphones.

After being intercepted by the FBI near Washington Square Park in a highly publicized episode in November 2023, Adams told the feds through his lawyer that he had left that phone at City Hall and forgotten the password to the device — after changing the code to it just the night before, the new records say. He told his scheduler to help him bring the phone to an Apple Store to get access back, but he ultimately never did so, Adams said through his lawyer.

But the phone’s location tracking showed the phone was not stationary at City Hall but actually traveled from City Hall, past Washington Square Park and then north to 29th Street before it was either put in airplane mode or turned off, the documents say.

“I respectfully submit that there is probable cause to believe that Adams made false statements about the location of the Adams Personal Cellphone through his attorney, thus committing certain of the Subject Offenses,” an agent wrote in a newly released document from March 2024.

The agent added that that violation constitutes “evidence of consciousness of guilt” on Adams’ part.

Adams’ indictment, the first against a sitting New York City mayor in modern history, mostly revolved around allegations that he took illegal campaign cash and bribes, like free luxury airline tickets, from Turkish government operatives in exchange for political favors. Adams has consistently denied those charges.

“Today’s unsealing of documents affirms what we have long known — Mayor Adams did nothing wrong. These documents also show that federal authorities made false, reckless accusations with absolutely no evidence in a relentless, shameless assault on the mayor,” Todd Shapiro, a spokesman for the mayor’s reelection campaign, said in a statement.

The new documents, which were unsealed late Friday at Manhattan Federal Court Judge Dale Ho’s order, reveal the feds were expanding their investigation in the days before Trump’s Department of Justice intervened and ordered prosecutors on Feb. 10 to dismiss the case so Adams could better help the president in his immigration crackdown.

Montgomery, who worked with Adams in the Police Department, pleaded guilty last year to state charges alleging he orchestrated a straw donor scheme in which he financially boosted the mayor’s 2021 campaign by giving money to it in the names of others, unlocking illicit public matching funds. Those charges came out of an investigation conducted by the Manhattan district attorney’s office that did not implicate the mayor in any wrongdoing.

The new search warrant records unsealed Friday reveal the feds suspected Montgomery had also engaged in a separate, but similar straw donor scheme involving Adams’ 2025 reelection campaign. Montgomery’s name is redacted in the records, but information about the circumstances of his guilty plea spelled out in the federal documents, including the date, charges and his home address, point to him.

The feds seized at least two phones from Montgomery, according to the new records. He was never charged with any wrongdoing as part of the federal probe, nor were additional charges brought against Adams in connection to Montgomery.

The feds wrote in the newly unsealed records they had reason to believe Montgomery was implicated in the 2025 scheme as he and Adams had continued to be in touch with each other about campaign fundraising after Adams became mayor in January 2022.

“Because [Montgomery] remained in contact with Adams into 2023, there is probable cause to believe that evidence of criminal activity by [Montgomery] relating to the 2025 campaign also exists,” an FBI agent wrote in an affidavit seeking to pull data from Montgomery’s phones confiscated during the search of his home.

Other records reveal the feds were able to get their hands on texts between Montgomery and Adams in which they referred to each other as “brother” and “Boss man.”

In one exchange from January 2022, Montgomery asked Adams to be appointed a deputy mayor. “Deputy mayors are in charge of several agencies. Not a small task,” Adams texted back, according to the new records.

Montgomery was ultimately never made a deputy mayor.

An attorney for Montgomery didn’t return a request for comment Friday. Kayla Mamelak, Adams’ spokeswoman at City Hall, referred comment to the mayor’s criminal attorney, Alex Spiro.

“This case — the first of its kind airline upgrade ‘corruption’ case — should never have been brought in the first place and is now over,” Spiro said in a statement.

The new records reveal other previously unknown law enforcement actions.

A judge signed off on a warrant to search the Fort Lee, New Jersey, condo that Adams shares with his longtime partner, former Department of Education official Tracey Collins, who allegedly benefited from some of the bribes he took. While the warrant did not directly name Collins, it described her job and said she was Adams’ partner. She has not been accused of any wrongdoing by the feds.

The new records also reveal a December 2024 raid at the Woodside, Queens, home of an executive of a health care company who allegedly reimbursed employees to donate money to Adams’ campaigns, a previously unknown example of illegal straw contributions, an affidavit from an FBI agent states.

The raid at the unidentified health care executive’s home was authorized by a judge after a person phoned in a tip to the FBI, according to the affidavit.

The tipster alleged being “a victim” and being “forced to make straw donations myself along with many others” to Adams’ campaigns “along with campaigns for other politicians,” according to an affidavit from an FBI agent.

The trove of search warrant documents got released a week later than originally expected, as Trump’s DOJ asked for an extra week to pull everything together after the records were initially due last Friday.

Trump’s DOJ officials secured the dismissal of Adams’ indictment on April 2 after arguing the case inhibited the mayor from helping in the president’s “mass deportation” agenda. That arrangement has led many to believe Adams is compromised, and DOJ officials never opined on the merits of the case against him in seeking its dismissal.

The Trump DOJ-led effort to kill the case ignited a sharp backlash, setting off waves off resignations inside the Manhattan U.S. attorney’s office, which indicted Adams in September 2024.

That included former interim U.S. Attorney Danielle Sassoon, who wrote in her resignation letter that Adams had entered into a corrupt quid pro quo with Trump to get rid of his case by offering immigration enforcement assistance in exchange for a dismissal.

Before the dismissal, prosecutors indicated in court and in filings that they planned to pursue additional charges against the mayor.
