Trump can't fire this 'deeply unpopular' official — and it's driving him mad: biographer

President Donald Trump is itching to fire one particular "deeply unpopular" cabinet official, but doing so could spell the end of his administration, according to one of the president's biographers.

Journalist Michael Wolff, who has written four books about Trump, argued during a new episode of "Inside Trump's Head," a podcast he co-hosts with Joanna Coles of The Daily Beast, that Trump wants to fire Health Secretary Robert F. Kennedy Jr. because of his anti-vaccine policies, which Wolff said are "deeply unpopular everywhere." However, firing Kennedy may prove to be too much for Trump to handle, as he is closely aligned with another MAGA heavyweight who is ready to take Trump's base from him.

"They don't want to fire him because ... the MAHA constituency is significant, they feel, to the Trump base," Wolff said. "So they want him to go away but not go away mad."

Wolff also noted that Kennedy is close with MAGA commentator Tucker Carlson, who is reportedly considering running for president in 2028. That alliance could be enough to bring down Trump, if Kennedy is released from the administration, he added.

"Tucker has become their enemy, and there's only so many enemies in their own base they can afford," Wolff said.
