The US Senate voted to confirm Marco Rubio as Secretary of State on Monday, making him the first official in Donald Trump's administration to be approved on his presidential inauguration day. The vote, which came just hours after Trump’s swearing-in ceremony, was unanimous at 99-0.

Rubio -- long known as a Russia and China hawk in the Senate -- has been accused of dialing back his interventionist foreign policy approach to align with Trump's positions and may face fresh criticism from opponents who believe he might prioritize serving as a yes man to president over serving the country.
