Sen. JD Vance (R-Ohio), 40, will ascend to first in line for the presidency on the coattails of Donald Trump’s successful bid for a second term, as the third-youngest vice president in American history and the first millennial to hold the office.

JD Vance is now just a heartbeat from the presidency—and that’s the heart of the oldest man ever elected to the White House.Just eight years ago, Vance was criticizing Donald Trump as a “fraud” and a “moral disaster” and reportedly told a friend he couldn’t decide whether the MAGA mogul was a “cynical a–hole like Nixon” or “America’s Hitler.

JD Vance, a 40-year-old senator who transformed himself from a biting critic of Donald J. Trump to one of his fiercest defenders, was elected the next vice president of the United States on Wednesday, becoming the third youngest and among the least experienced and most polarizing politicians ever to hold the office.
