Trump just reached a 'moment of demarcation' that signals the end is near: biographer

President Donald Trump has reached a "moment of demarcation" that signals the end of his presidency is near, according to one of the president's biographers.

Michael Wolff, who has written four books about Trump, noted during a new episode of "Inside Trump's Head," a podcast he co-hosts with Joanna Coles of The Daily Beast, that Trump has had a "rough couple of weeks" as his losses continue to pile up. Wolff pointed to issues such as Congress curtailing his war powers in Iran, and his seeming inability to escape the Jeffrey Epstein saga.

"I've more and more understood this and appreciated this, and I think it's an important moment. It's a moment of demarcation," Wolff said. "It's a 'two things can be true at the same time' moment. Trump is going to continue to be mendacious and dangerous and damaging to all kinds of things, but at the same time, very clearly, as clearly as can possibly be, this Trump enterprise is coming apart. And I think we're right at the center."

"And it all sort of brings this together in his falling poll numbers, the fact that he is in trouble on all of the foundational policies of his administration — that he could fix the economy," Wolff said. "Immigration was his issue, the issue that was fueling him instead of the issue that is causing him now so many problems, so many problems with his base, the health care issues also causing him problems. It's one problem after another after another that he cannot surmount."
