President Donald Trump "is weak and getting weaker" after caving to far-right demands and shutting down the federal government, Washington Post columnist Jennifer Rubin explained on MSNBC's "AM Joy" on Saturday.

Anchor Joy Reid explained Republicans "fear Fox News" even though they could help their own popularity by passing a clean bill to keep the government open.

"[Trump] is weak and he is getting weaker by the moment," Rubin argued.

"And the fact that the Russia investigation, the other investigations, are closing in..." she continued.

"Is that what this is about?" Reid interrupted.

"Yes, absolutely. He needs desperately to hold on to those people," Rubin answered. "If those people break with him, then he is toast -- I think he is toast, anyway."

"But I think the more that he is under siege, the more he lose voices of sanity around him -- [Jim] Mattis and everybody else -- the more comes out through Michael Cohen, through [Mike] Flynn, the more desperate he becomes to please those people," she explained.

"And it is not a situation in which Fox News follows the White House. The White House follows Fox News," she added.

"Rush Limbaugh is bragging that he basically told him what to do," Reid noted.

"Maybe Democrats should go negotiate with Rush Limbaugh, because apparently he checks with him," Rubin suggested. "He is the principal here, I guess."
