DJT doing the same with Pence as he did with Raffensperger phone call - giving every chance for known traitors to flip and do the right thing. If Pence were solidly behind Potus he wouldn't be tweeting about Pence like this.
The only "right thing" Pence can do now, to atone for his treason, is the Samson option - public confession bringing down "the whole diseased temple" on himself and the cabal. Or, to use another Biblical illustration from the book of Esther, Pence (Hamaan) will be "hanged on the gallows" that he prepared for Trump (Mordecai).
