“In this case, we have not assessed the credibility of the potential for disturbances, and we do not have any knowledge of the President’s decision-making process.”

A group has called for a “Nobody is Above the Law” rally in Pittsburgh if Mueller gets fired, but it’s unclear whether the police response is based on that.

“We are getting ready in Pittsburgh to respond quickly and forcefully to a clear obstruction of justice,” the group says online. It says simultaneous emergency rallies are planned nationwide.

Trump on Wednesday downplayed speculation that he’s planning to fire Mueller or Deputy Attorney General Rod Rosenstein, who is overseeing the investigation.

“They’ve been saying I’m going to get rid of them for the last three months, four months, five months and they’re still here,” the President told reporters. Speculation on Mueller’s fate grew after the FBI raided the house, office and hotel room of Trump’s personal attorney, Michael Cohen, last week.

Since then, the President has openly mulled whether to fire Mueller and repeated his attack on the special counsel’s investigation as a “witch hunt.” Trump is also considering axing Rosenstein as a way to limit Mueller’s investigation, multiple people familiar with the discussions told CNN.

White House press secretary Sarah Sanders told reporters last week that Trump believes he has the power to fire Mueller.

Rosenstein, the Justice Department’s No. 2 official, inherited the oversight of the special counsel’s probe into Russia and any potential links it had with Trump campaign associates. His boss, Attorney General Jeff Sessions, recused himself from investigating matters related to the presidential campaign.
