James Clapper, the former director of national intelligence, has accused Donald Trump of placing American democratic institutions “under assault” following the sacking of James Comey – and cautioned that the former FBI director’s removal is “another victory” for Russia.
The forceful criticism comes as the Department of Justice began screening candidates for Comey’s replacement and Democrats renewed calls for a special prosecutor to oversee an investigation into Russia’s interference in the 2016 election.
“I think in many ways our institutions are under assault,” Clapper told CNN’s State of the Union on Sunday. “Both externally, and that’s the big news here, is Russian interference in our election system. And I think as well our institutions are under assault internally.”
When asked to clarify if the internal assault came from the president directly, the former spy chief added: “Exactly.”
In a later interview on ABC news, Clapper added that “the Russians have to consider this [Comey’s sacking] as another victory on the scoreboard for them”.
The bleak assessment came days after Trump claimed on Twitter that Clapper had determined “there is no collusion” with reference to his presidential campaign and Russia, a characterization that Clapper has refuted.
The former national intelligence director, who served under the Obama administration from 2010 until Trump’s inauguration, said during a March interview that he had no knowledge of any collusion between the Republican’s campaign and Russian operatives. He has since clarified that during his time in office he was also unaware of an FBI investigation into such collusion, adding on Sunday: “I don’t know if there was collusion. And I don’t know of any evidence to it so I can’t refute it and I can’t confirm it.”
An NBC/Wall Street Journal poll released on Sunday found only 29% of Americans approved of Comey’s firing, while 78% supported an independent commission or special prosecutor to investigate Russia’s interference in the election.
The result is likely to bolster Democrats. Senate minority leader Chuck Schumer renewed calls for a special prosecutor, and raised questions over whether US attorney general Jeff Sessions had violated the terms of his recusal from the Russia investigation by recommending the removal of Comey.
Sessions recused himself after it emerged he had failed to disclose contacts between himself and Russian ambassador Sergey Kislyak during the 2016 campaign.
“The actions of the last week make all the more reason that he should not be attorney general,” Schumer told CNN on Sunday.
Senate Democrats are discussing the possibility of blocking Trump’s eventual nominee to replace Comey until a special prosecutor is appointed. Schumer on Sunday indicated he was supportive of such a move.
Comey has rejected an invitation to testify in a closed door Senate committee hearing next week, but has reportedly expressed a desire to testify in public at a later date. Clapper said on Sunday he had been in contact with the former FBI director by email, but declined to characterize the nature of their conversation.
Comey has made no public comment since he was sacked on Tuesday, but was spotted on Saturday at a matinee performance of the Broadway musical Fun Home, which is currently on tour in Washington DC.
On Saturday at least eight candidates for the vacant FBI position met Sessions and deputy attorney general Rod Rosenstein at the justice department. The list included the acting FBI director Andrew McCabe, Alice Fisher, a high-ranking justice department official in the George W Bush administration, Texas Republican senator John Cornyn, and former Republican congressman Mike Rogers, who is also a former FBI agent.
Rogers has won the endorsement of the FBI agents association, which represents 13,000 former and current agents and has ties to Trump surrogate and former New York mayor Rudy Giuliani.
Trump told reporters on Air Force One on Saturday that he predicted the selection and nomination process “is going to go quickly”.
Schumer, on Sunday, argued that the eventual nominee should “not be a partisan politician” and “should be someone with courage” to stand up to “attempted interference” with the Russia investigation.
Schumer’s call was echoed by at least one Republican senator on Sunday, as Lindsey Graham told NBC’s Meet the Press he believed the new FBI director should be someone who “comes from within the ranks or has such a reputation that has no political backgrounds at all, that can go into the job on day one”.
Graham added of the ongoing investigation into Russia’s interference in the election: “The president needs to back off here and let the investigation go forward.”
