Donald Trump called Zachary Czubak and Patrick Fleming onto the stage at a campaign rally in Wasilla and signed their pardon documents. The two Alaska diesel mechanics had been convicted in a federal case involving allegations that they violated the Clean Air Act.
Trump said the two mechanics had been facing 10-year prison sentences for repairing engines and called the previous federal policy unfair. He argued that emissions systems can cause vehicles to break down in the extreme northern cold.

Charges covered at least 37 diesel trucks
Czubak and Fleming were partners in Arm Rippin Toys, a repair business in Anchorage. The two mechanics, along with their third partner, Michael Wayne Hanzuk, pleaded guilty in 2022 to conspiring to violate the Clean Air Act.
Prosecutors alleged that the business removed mandatory emissions-control equipment from at least 37 diesel trucks and altered monitoring components between July 2019 and September 2020. Fleming said on stage that the pardon meant a great deal to him and that their goal had been to help drivers.

Justice Department changes policy
Trump’s pardon came after a policy change announced by the U.S. Justice Department in January. The department said it would no longer seek criminal charges against people involved in devices that disable the emissions-control systems of diesel vehicles.
The department said future enforcement would be limited to civil penalties.
