Missouri Secretary of State Jay Ashcroft said that while he didn’t want to do it, he had to remind people of how “severe” the situation is.

A top Republican official in Missouri is threatening to remove President Joe Biden from appearing on the ballot as retaliation for the determination in two other states that Donald Trump doesn’t qualify because he “engaged in insurrection.”

“What has happened in Colorado & Maine is disgraceful & undermines our republic,” Missouri Secretary of State Jay Ashcroft wrote on the social media site X on Friday. “While I expect the Supreme Court to overturn this, if not, Secretaries of State will step in & ensure the new legal standard for @realDonaldTrump applies equally to @JoeBiden!”

Ashcroft’s post came shortly after the Supreme Court agreed to review a decision by Colorado’s high court that found Trump could be barred from the state’s primary ballot because of his actions leading up to the Jan. 6, 2021, attack on the U.S. Capitol.
