In June 2022, dozens of armed federal agents — flown in from California, Washington, and Oregon — raided a diesel repair shop called Matanuska Diesel in Wasilla, Alaska. The target wasn't a drug operation or a terror cell. It was a business that fixes trucks.
On July 4, 2026, President Trump pardoned the owner and his fellow mechanics.
MacKenzie "Mac" Spurlock is a Wasilla diesel mechanic, a small business owner, and an Alaska Air National Guard veteran. His crime, according to Biden's Justice Department, was modifying diesel trucks in ways that violated the Clean Air Act. Nine individuals total were convicted under the same charges — blue-collar workers whose trade put them on the wrong side of the previous administration's environmental enforcement agenda.
As reported by WLT Report, Trump announced the pardons on Truth Social, describing the recipients as people "prosecuted for repairing vehicles under the previous administration." Eleven people total received pardons on Independence Day. Nine of them were diesel mechanics convicted under the Clean Air Act.
Sen. Dan Sullivan of Alaska welcomed the decision, describing Spurlock as "a Wasilla diesel mechanic, small business owner, and Alaska Air National Guard veteran" who never should have been targeted. Sullivan has since introduced the Cold Weather Diesel Reliability Act, legislation aimed at preventing the federal government from prosecuting mechanics for modifications that are standard practice in states where trucks operate in extreme cold.
The backstory matters here. Diesel modifications — removing or altering emissions equipment — are common across rural America and especially in cold-weather states where factory emissions systems can force trucks into "limp mode" at speeds as low as 5 mph. For mechanics like Spurlock, these modifications aren't ideological. They're how you keep a truck running when it's forty below.
Biden's EPA didn't see it that way. The agency treated emissions modifications as criminal violations and deployed armed enforcement raids that looked more appropriate for a cartel bust than a truck shop. Fox News and CBS News both covered the Matanuska Diesel raid at the time — federal agents with weapons drawn, descending on a small Alaskan business over catalytic converters and exhaust systems.
The mechanics pled or were found guilty. They had felony records. Some lost their businesses.
Trump could have signed the pardons on any Tuesday. He picked the Fourth of July. Sullivan could have introduced his bill without the backstory. He led with the raid.
When the government sends armed agents from three states to kick in the door of a truck shop in Wasilla, the question was never really about emissions standards. It was about what the federal enforcement apparatus decides to point itself at — and who gets to redirect it.
