Top staffers from Hillary Clinton's campaign slammed President Trump's dismissal of former FBI Director James Comey and said it was a sham that the administration is blaming it on a controversial July 2016 press conference.

Brian Fallon, Clinton's press secretary during the campaign, said he still feels Comey's handling of the Clinton email controversy was a "travesty." But, to blame Comey's dismissal on a press conference given in July 2016 — in which Comey detailed the FBI's findings in the email investigation but said there would be no charges in the case — is a farce, he said.

"All these months later it still stands out that Director Comey's handling of the Clinton email controversy was a travesty," Fallon said.

"But, the timing and the nature of this firing that the Trump administration's announcing now belies that this has anything to do with the Clinton email investigation."

He added, "This is clearly a president who is feeling the heat of the FBI's ongoing Russia investigation."

Deputy Attorney General Rod Rosenstein wrote in his memo that Comey went too far outside the scope of his duties and defied then-Attorney General Loretta Lynch with that press conference.

Fallon said Rosenstein has a great reputation as an independent and fair attorney, and he had no idea why he would attach his name to such a letter.

"Donald Trump is trading on the deputy attorney general's strong, independent reputation and trying to pretend that is the reason he's imposing this firing on Jim Comey," Fallon said, "when really he's trying to get out from under the Russia investigation."

Robby Mook, Clinton's campaign manager, added that he is scared of what Trump is doing in office.

"Twilight zone. I was as disappointed and frustrated as anyone at how the email investigation was handled. But this terrifies me," he tweeted."
