Secretary of Defense Ashton Carter said he laughed when he saw the Vice President engaged in an infamous “close-talk” with his wife while he was being sworn in.

“They know each other extremely well,” Carter told Savannah Guthrie in an interview with NBC’s TODAY on Tuesday. “We’re great friends of the Bidens.”

Cringeworthy images of Vice President Joe Biden leaning into Mrs. Carter’s ear during his swearing in ceremony went viral in mid-February. It wasn’t, however, the first time the veep got a little too close for comfort.

In the interview with Guthrie, Carter also addressed the ongoing negotiations with Iran over obtaining nuclear weapons. If a deal isn’t reached by the Tuesday deadline, Carter said, “the military option will remain on the table.” He added, “if there is a good deal to have, obviously it’s worth waiting for and completing the negotiations.”
