Donald Trump has endorsed Mike Lindell’s bid for Minnesota governor, calling the MyPillow founder “one of America’s greatest and most hard working Patriots” in a Truth Social post on Wednesday.

Trump described Lindell as someone who had “sacrificed” more than almost anyone else “in fighting for our country, especially when it comes to Election Integrity”, invoking Lindell’s years spent promoting discredited claims about the 2020 election. Trump said Lindell “will MAKE MINNESOTA GREAT AGAIN” and gave him full-throated support ahead of the state’s 11 August Republican primary, where early voting is already under way.

The backing lands as Lindell trails in general election polling. A Star Tribune/KARE 11/Hubbard School Minnesota poll conducted in June found the Democratic senator Amy Klobuchar leading Lindell 53% to 36% in a hypothetical matchup, with 11% undecided, making it her strongest showing against any of the Republican contenders tested.

That should help pillow sales.
