Such an action could potentially further Trump’s goal of trying to put greater limits on special counsel Robert Mueller…

Firing Mueller could throw Trump’s presidency into crisis and not all of Trump’s legal advisers are on board. One source said Rosenstein wouldn’t be fired.

But some of Trump’s legal advisers are telling him they now have a stronger case against Rosenstein. They believe Rosenstein crossed the line in what he can and cannot pursue. And they consider him conflicted since he is a potential witness in the special counsel’s investigation because he wrote the memo that justified firing former FBI Director James Comey. The legal advisers also believe they have successfully argued to the American public that the FBI is tainted and think they can make the same case against Rosenstein.
