WASHINGTON − The first time Vice President JD Vance walked into the Oval Office, he noticed the drapes ("dark and gloomy") – but he insists he’s not measuring them for a future turn behind the Resolute Desk.

“I've gotten a lot of good on-the-job training over the last 200 days,” Vance said in an exclusive interview with USA TODAY on Aug. 27, when asked if he was ready to assume the role of commander-in-chief.

His boss, after all, is the oldest person to be sworn in as president of the United States. President Donald Trump was 78 when he began his second term in office.

“The president is an incredibly good health,” said Vance. “He's got incredible energy.”

The wide-ranging interview covered topics including his televised spat with Ukrainian President Volodymyr Zelenskyy, the Taylor Swift-Travis Kelce engagement, and the president's controversial efforts to oust a Federal Reserve governor.
