Driving the news: In a phone interview on Sunday afternoon, Scaramucci compared Trump to a melting nuclear reactor and said he may support a Republican challenger to Trump.

“We are now in the early episodes of ‘Chernobyl’ on HBO, where the reactor is melting down and the apparatchiks are trying to figure out whether to cover it up or start the clean-up process,” Scaramucci said.

“A couple more weeks like this and ‘country over party’ is going to require the Republicans to replace the top of the ticket in 2020.”
