Mayor Eric Adams accompanied the Trump administration’s transportation secretary, Sean Duffy, on a train ride today to see the subway up close.

The ride lasted just two stops — they took the B train from Brooklyn’s Dekalb Station and went over the bridge to the Broadway-Lafayette station in Manhattan.

Adams and Duffy discussed policing and safety. The ride comes following weeks of harsh criticism from Duffy about crime in the subway and threats to pull federal funding from the MTA.

Duffy also again criticized the congestion pricing program in Manhattan he is trying to stop.

“That’s fundamentally unfair. It’s classist. It’s elitist,” Duffy said.

Duffy also said he’d sick Elon Musk’s DOGE on the MTA to root out fraud and waste in the billions of federal dollars the transit agency receives.

“We must make sure that we feel safe,” Adams said.

City Hall kept the mayor's and secretary’s whereabouts hidden from most reporters. Gov. Kathy Hochul, who oversees the MTA, was also never invited.

“Secretary Duffy has literally no idea what he’s talking about,” Hochul spokesman Avi Small said in a statement. “As Mayor Adams and most New Yorkers know, Governor Hochul stepped up to add NYPD officers and security resources on public transit. Now, subway crime has declined by double digits and ridership continues to grow.”

The MTA chief, Janno Lieber, was also in the dark and went searching for Duffy and Adams on the subway. He never found them.

For Adams, face time with a Trump cabinet official capped off a week where the Trump Justice Department successfully got his corruption case dismissed. The mayor also endorsed a book from Trump’s FBI director about the deep state and announced his reelection campaign as an independent.
