Within a few hours on Friday, November 21, Donald Trump embraced one of his fiercest critics and lost one of his most valuable allies. While New York City's mayor-elect Zohran Mamdani's visit to the White House in the afternoon, and Marjorie Taylor Greene's resignation from the House of Representatives in the evening were not directly connected, both illustrated a peculiar period the US president was experiencing – torn between political setbacks and risky initiatives.

Greene's decision to leave her seat in the House on January 5, where she had served continuously since 2020, was undoubtedly the most unexpected news of the day. The split with Trump seemed definitive, but few anticipated the Republican would slam the door so publicly, posting a scathing four-page letter on social media.

"I have too much self respect and dignity, love my family way too much, and do not want my sweet district to have to endure a hurtful and hateful primary against me by the President we all fought for, only to fight and win my election while Republicans will likely lose the midterms," wrote the Georgia lawmaker.
