Donald Trump has publicly called it quits with one of his most stalwart MAGA-world supporters, calling Georgia Rep. Marjorie Taylor Greene “‘Wacky’ Marjorie” and saying he would endorse a challenger against her in next year’s midterms “if the right person runs.”

The dismissal of Greene — once the epitome of “Make America Great Again,” sporting the signature red cap for President Joe Biden’s 2024 State of the Union address and acting as a go-between for Trump and other Capitol Hill Republicans — appeared to be the final break in a dispute simmering for months, as Greene has seemingly moderated her political profile.

The three-term U.S. House member has increasingly dissented from Republican leaders, attacking them during the just-ended federal government shutdown and saying they need a plan to help people who are losing subsidies to afford health insurance policies.
