I've been convinced for months that these rumors are put out there by Democrats and RINO co-conspirators who realized a long time ago that goading Trump into firing Mueller is the only way to mount any credible campaign to remove him from office.
It’s too late if you wait for court documents.
Firing Mule is a 4 day outrage cycle then declassify all his supposed great leads or we spend the next 20 years in an Oliver Stone conspiracy cyle.
