Sen. Marco Rubio, Donald Trump’s pick for secretary of state, is widely expected to win Senate confirmation to the post.

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.

Marco Rubio used to clash with President-elect Donald Trump, but now seems headed toward Senate confirmation as secretary of state.

A decision by Donald Trump to continue to hand out political rewards in the form of appointments to be a "special envoy" to U.S. allies has foreign diplomats wary of who they should listen to and who they should ignore.
