Schumer probably knows why Berman was fired. The bigger an issue he makes of the new person's confirmation, the more likely all the Berman shit will come out.
Graham handing Schumer a tar baby here, I think.
After Berman's kneejerk rection to being fired, refusing to leave, someone told him to STFU and GTFO while the getting's good. Didn't these guys just get burned in the Linnick firing? My guess is Chuck (and Chuck's handlers) wants no part of this.
