MuellerRepublicans needs only to ask Trump one question.
"Did you try to fire me?"
If Trump sys, "Yes", that is obstruction of justice.
If Trump says "NO", that is perjury.
In reality, the party isn't seeking honest answers anymore but would rather promote a platform for midterms elections, November won't be a pretty picture for the GOP solely for the fact that America is tired of the dishonesty & hatred coming from Trump and the party's lack of intervention to keep Trump in check.
