You have already sniffed too many of those fumes to think clearly.
You have zero evidence that Trump was wholesale lying—which is a wholly different phenomenon than playing the press—when he said Sessions should have told him he planned to immediately recuse. Rosenstein participated in the felonious FISA warrant attempted coup, the purpose of which was to ensure a Hillary victory. If Trump had wanted a Trump-hating Hillary-fixer as Acting AG, he would have chosen Rosenstein himself. But he chose a person he mistakenly thought was on his side, and Sessions instantly—without providing his boss the minimal professional courtesy of a forewarning—demoted himself to the deputy slot and turned all the big, crucial issues over to Rosenstein.
