Biden Tries to Turn the Tables on Trump: ‘He’s About as Old as I Am’

President Biden has come up with a new defense against claims that he is too old to run for another term: At least he knows who his wife is — as opposed to “the other guy.”

As he expands his efforts to reassure voters that he is fit for another four years, Mr. Biden took a turn on the talk show circuit, using an appearance on “Late Night With Seth Meyers” on NBC to poke his challenger, former President Donald J. Trump, on his own struggles with memory.

In a playful but pointed interview aired early Tuesday morning, Mr. Meyers sought to help the president address the age issue, which polls show is an important drawback in the minds of most voters. Mr. Meyers jokingly told the president that he had obtained classified information indicating that “you are currently 81 years old.”

Mr. Biden went along with the joke. “Who the hell told you that?” he asked. “That’s classified!”

He then went on to jab Mr. Trump, who is 77, over a video in which he seems to call his wife, Melania Trump, by another name. “You got to take a look at the other guy,” Mr. Biden said. “He’s about as old as I am, but he can’t remember his wife’s name.”

Turning more serious, Mr. Biden added that the contest is not about how old the candidates are. “It’s about how old your ideas are,” he said. “Look, this is a guy who wants to take us back. He wants to take us back on Roe v. Wade. He wants to take us back on a whole range of issues that are — 50, 60 years, they’ve been solid American positions.”

The president has been on the defensive about his memory in recent weeks, particularly since a special counsel, in a report on Mr. Biden’s handling of classified documents, explained that one reason he would not charge Mr. Biden is because he would come across to a jury
