The Tonight Show Starring Jimmy Fallon, alongside her daughter Chelsea Clinton, 42, on Tuesday night.As part of the interview, the pair took part in a Mother Daughter Challenge, where they had to answer a series of questions asked by Fallon.At one point during the segment, Clinton, 74, was asked about her “craziest family vacation memory.”Taking a second to think, the mom-of-one remembered the time she and Bill managed to leave Chelsea in the Kremlin sometime during Bill’s time in office from 1993 until 2001.“I hope she [Chelsea] doesn’t remember this because it was pretty traumatic,” the former Secretary of State began. “We took her to Russia when we went on a state visit when Bill was president, and there were the formal goodbyes so Bill and I were ushered into the Beast, the big limousine, to head to the airport, not knowing that we had left her behind.
