Vice President JD Vance has sworn in Marco Rubio as secretary of state, the first of President Trump’s cabinet nominees to take the job.

Former Sen. Rubio (R-Fla.) said Trump’s primary priority will be furthering the United States’ interests and that anything the government and State Department do must make the country stronger, safer or more prosperous.

“If it doesn’t do one of those three things, we will not do it,” Rubio said.

Vance, who served in the Senate alongside Rubio, called him a “bipartisan solutions seeker.”
