Putin used Wednesday’s interview to downplay speculation about Biden’s cognitive health, recalling when the two met in Switzerland in June 2021, less than a year before Russia’s full-scale invasion of Ukraine.

“When I met with Biden in Switzerland — it was, indeed, a few years ago, three years — even then there were talks about him being incompetent. I saw nothing of the sort. Yes, he glanced at his notes. Honestly, I glanced at mine too,” Putin said. “There’s nothing to it.”

Putin said he is less concerned with his U.S. counterpart’s health than with Washington’s political position, which he said was “extremely harmful and erroneous.”

Trump, and Biden’s other Republican opponents, have seized on the president’s mental abilities to argue he isn’t fit to continue to hold office after a series of gaffes confusing world leaders and a recent Justice Department special counsel report that described him as a “well-meaning, elderly man with a poor memory.”

Trump himself has faced questions about his age and mental acuity, with Biden’s campaign suggesting the former president may be struggling with diminished cognition and frequently calling him “confused.”

 “Mr. Putin should stay out of America’s elections,” said White House spokesperson Andrew Bates.
