Attorney General William Barr said in his testimony before the Senate Judiciary Committee on Wednesday that he believes the president can fire any prosecutor investigating him should he feel the accusations against him are false.

The attorney general has already drawn the ire of many congressional Democrats for favoring President Donald Trump in Special Counsel Robert Mueller‘s Russia investigation.

“The point I was trying to make earlier is that, in the situation of the President, who has constitutional authority to supervise proceedings, if in fact a proceeding was not well founded, if it was a groundless proceeding, if it was based on false allegations, the President does not have to sit there, constitutionally, and allow it to run its course,” Barr, who previously worked in George H W. Bush‘s Justice Department, said during his Senate testimony. “The President could terminate that proceeding, and it would not be a corrupt intent, because he was being falsely accused.”

Among those who reacted to Barr’s sentiment was Hillary ClintonThe former secretary of state and 2016 presidential candidate told MSNBC’s Rachel Maddow on Wednesday night that she believed Barr’s comments were a sign of “the road to tyranny.”

“That is what authoritarians believe and those who service them argue,” said Clinton of Barr’s remarks.

Several Democrats have called for Barr’s resignation. Barr wrote a memo as a private citizen nearly one year ago saying he believed the obstruction of justice probe against Trump was “fatally misconceived.”
