President Joe Biden and President-elect Donald Trump spoke on the phone over the Thanksgiving holiday last week, according to two people familiar with the call.

The previously unreported phone call marks the only known time Biden and Trump have spoken since the president-elect visited the White House for a meeting in the Oval Office on Nov. 13.

The two people familiar with the conversation said Trump called Biden to wish him a happy Thanksgiving. They said the conversation between the two leaders was brief and not substantive.
