(CNN) Former acting FBI Director Andrew McCabe said Sunday that Deputy Attorney General Rod Rosenstein "offered to wear a wire into the White House," resurfacing one of the most controversial and disputed episodes of the Justice official's tenure.

McCabe told CBS' Scott Pelley on "60 Minutes" that Rosenstein said, "'I never get searched when I go into the White House. I could easily wear a recording device. They wouldn't know it was there.'"

As CNN previously reported, Rosenstein denies he pursued any recording, and a source in the room for these conversations said Rosenstein was being sarcastic.

But in McCabe's view, Rosenstein "was not joking," disputing the narrative it was not seriously considered at the time.

"He was absolutely serious," McCabe told Pelley. "And in fact, he brought it up in the next meeting we had. I never actually considered taking him up on the offer. I did discuss it with my general counsel and my leadership team back at the FBI after he brought it up the first time."
