Miller is challenging Rep. Anthony Gonzalez, who has represented Ohio’s 16th Congressional District since 2019.
The former president previously described Miller as “a wonderful person who did a great job at the White House.”
He “will be a fantastic Congressman,” Trump said of Miller in February. “He is a Marine Veteran, a son of Ohio, and a true PATRIOT.”
Trump’s statement also criticized Gonzalez, who was among a small group of Republicans who voted to impeach Trump for inciting the Jan. 6 riot in Washington, D.C. Trump was ultimately acquitted of the charges.
“Current Rep. Anthony Gonzalez should not be representing the people of the 16th district because he does not represent their interest or their heart. Max Miller has my Complete and Total Endorsement!” he wrote.
In January, Gonzalez released a statement claiming Trump was directly responsible for the Capitol riot.
“The President of the United States helped organize and incite a mob that attacked the United States Congress in an attempt to prevent us from completing our solemn duties as prescribed by the Constitution,” Gonzalez said in the statement.
“During the attack itself, the President abandoned his post while many members asked for help, thus further endangering all present,” he added. “These are fundamental threats not just to people’s lives, but to the very foundation of our Republic.”
