Vice President JD Vance backed President Donald Trump‘s opening moves in his first interview since being sworn in. In an interview with CBS News’s Face the Nation, Vance clashed with host Margaret Brennan over issues such as immigration and recent moves by the U.

As he prepares to become the nation’s first millennial vice president, JD Vance is already a budding kingmaker in Republican politics and the presumptive heir to the “Make America Great Again” movement.

At age 40, a relative newcomer who made his name on the campaign trail for his fierce attacks on Democrats is first in the line of succession for president.

JD Vance’s first sit-down interview as vice president has been granted to Margaret Brennan, the moderator of CBS’ “Face The Nation.” The exchange will air on Sunday. But conservatives on social media expressed their unhappiness at the move.
