President Donald Trump on Friday pardoned six people convicted in federal emissions cases, saying they were victims of what he called the Biden administration's "Weaponization and Stupidity" in punishment for "fixing their car."

Trump announced the pardons in a Truth Social post, declaring that the six had been unfairly prosecuted and imprisoned under then-President Joe Biden.

"It is my Great Honor to have just signed Pardons for six people who were persecuted by the Biden Administration, and were in, or being sent to, prison, for 'fixing their car,'" Trump wrote. "While I know this sounds ridiculous, it is nevertheless a fact, and part of the Weaponization and Stupidity that our Country had to endure during four long years of Sleepy Joe Biden. I AM SETTING THEM ALL FREE, RIGHT NOW!"

The pardons come as the administration continues to roll back federal environmental enforcement priorities and what it describes as politically motivated prosecutions.

"President Trump is the ultimate decider on any clemency related actions," a White House official told CBS News ahead of the pardons.

Last year, Trump pardoned Wyoming mechanic Troy Lake, who served seven months in prison for violating federal emissions laws after disabling pollution-control equipment on diesel engines.

"We think this type of case is an example of government overreach," attorney Stewart Cables told CBS. "That's why we are trying to get these pardons."

Earlier this year, Todd Blanche, who at the time was deputy attorney general, ordered federal prosecutors to drop the remaining criminal cases involving aftermarket "defeat devices" used to modify diesel emissions systems, saying the move would "ensure consistent and fair prosecution under the law, as well as to ensure the best use of [Justice] Department resources."

Trump also signed a June 29 executive order directing the Environmental Protection Agency to deprioritize civil enforcement involving emission-control tampering.

According to CBS, Trump is also weighing other clemency requests, including one from music producer Sean "Diddy" Combs, who is serving a federal prison sentence of just over four years at Fort Dix, New Jersey, after his conviction last year on two counts of transportation to engage in prostitution.

He was acquitted of the more serious charges of sex trafficking and racketeering conspiracy.

Administration sources told the outlet no decision has been made.

Grammy Award-winning rapper Pras Michel of the Fugees and Malaysian financier Jho Low are also reportedly seeking presidential pardons.
