“...firing Mueller would only serve the interests of the impeachment crowd...”
Exactly. President Trump will not fire Mueller - if anything happens next week, Mueller will be closing the investigation.
I agree. No way is Trump going to fire Mueller just as his case is winding down; or at least should be.
Trump and Sessions should have a heart to heart about the future though. Sometime after Jan 20th; Sessions should resign but offered another position in the cabinet... possibly as an advisor/consultant.
