Republican senators—including Sens. Lindsey Graham (R-SC) and Chuck Grassley (R-IA)—have made recent statements indicating their cooling on Attorney General Jeff Sessions, seemingly a result of an aggressive lobbying campaign by President Donald Trump.

According to a Wednesday Politico report, Trump has hitched onto Graham and Grassley’s anger with Sessions for blocking their criminal reform bill, venting his frustration with his attorney general to them and any other senator who will listen.

His lawyers have reportedly also grown weary of trying to hold the furious President back from ousting Sessions, maintaining the notion that if Special Counsel Robert Mueller wants to build a case around Trump’s intimidation and bullying of the attorney general, he already has enough evidence to do so.

Per Politico, though recusing himself from Mueller’s probe was Sessions’ greatest sin in Trump’s eyes, the President also hates his southern accent and lack of Ivy League background. He apparently tells aides that Sessions “talks like he has marbles in his mouth.”

It is unclear if Congress would be able to confirm a replacement for Sessions this fall due to a massive workload, but as Republican senators leave Sessions’ side, it is looking increasingly likely that Trump is nearing the inevitable culmination of months of festering anger.
