A Politico/Morning Consult poll finds 48 percent think it would be wrong to fire Mueller. And beleaguered he should be, since the President who selected him is his "beleaguerer in chief", given the President's comments to The New York Times that Sessions should never have recused himself from the Russian Federation investigation and that had the President known of Sessions' intentions in this regard, he never would have appointed the senator from Alabama to his prestigious and powerful position in the first place.
Washington Post: Trump team seeks to control, block Mueller's Russian Federation investigation - "Some of President Trump's lawyers are exploring ways to limit or undercut special counsel Robert S. Mueller III's Russian Federation investigation, building a case against what they allege are his conflicts of interest and discussing the president's authority to grant pardons, according to people familiar with the effort". Twenty-two percent think it would be appropriate.
Only 29 percent of Republicans say it would be inappropriate, compared to 37 percent who say it would be an appropriate move to fire Mueller. But another one-third of voters don't have an opinion or don't know.
The poll was conducted July 20-24 among almost 4,000 registered voters and has a margin of error of plus-minus 2 percentage points. The margin of error is 2 percent.
