Sen. Claire McCaskill, D-Mo., said Thursday that Deputy Attorney General Rod Rosenstein knew FBI Director James Comey was going to be fired before he wrote his memo that made the case for his ouster.
McCaskill made the revelation to reporters following a rare full-Senate meeting with Rosenstein.
"He knew that Comey was going to be removed prior to him writing his memo," she said.
Sen. Dick Durbin, D-Ill., also confirmed McCaskill's statement, by saying that Rosenstein "knew it the day before."
President Trump has already admitted that he was "going to fire" Comey no matter what the memo said. Democrats have pointed to that as evidence that Trump was trying to hinder the FBI's probe into Russia, but Trump and other Republicans say they were unhappy with Comey's failure to charge Hillary Clinton for her use of private emails and the resulting leak of classified information.
