McCabe, in his interview with "60 Minutes," said Rosenstein was discussing "counting votes or possible votes" to invoke the Constitution's 25th Amendment, which allows Cabinet members to seek the removal of a president if they conclude that he or she is mentally unfit.
Though McCabe wouldn't confirm that Rosenstein was plotting to get rid of Trump, he said: "What I can say is the deputy attorney general was definitely very concerned about the president, about his capacity and about his intent at that point in time."
The Justice Department issued a statement Thursday that did not deny the conversation but that said Rosenstein believes "there is no basis to invoke the 25th Amendment, nor was (he) in a position to consider invoking the 25th Amendment."
CBS News posted the excerpt of its interview after ex-FBI official McCabe issued a statement saying comments of his on the subject had "been taken out of context and misrepresented." The interview will air Sunday on "60 Minutes."
CBS released a story Thursday about its interview in which correspondent Scott Pelley said McCabe had confirmed a discussion about the Constitution's 25th Amendment. But the transcript of that section of the interview was not released until Friday, after McCabe spokeswoman Melissa Schwartz sought to downplay McCabe's involvement in any discussions about a potential removal of the president.
"Certain statements made by Mr. McCabe, in interviews associated with the release of his book, have been taken out of context and misrepresented," the statement said. "To clarify, at no time did Mr. McCabe participate in any extended discussions about the use of the 25th Amendment, nor is he aware of any such discussions."
The interview was done ahead of the release next week of McCabe's book about his time in the FBI, "The Threat: How the FBI Protects America in the Age of Terror and Trump."
