President Donald Trump has endorsed MyPillow founder Mike Lindell for Minnesota governor, praising him as “one of America’s greatest and most hard working Patriots” and giving formal backing to a fellow election denier a day before the Republican president delivers a national address he says will focus on election security.

Lindell established his national profile from his TV advertising campaign as the MyPillow Guy and has been one of Trump’s most outspoken supporters, echoing the president’s false claims that his 2020 election defeat to Democrat Joe Biden was fraudulent.
