Trump Announces ExxonMobil CEO Rex Tillerson as Secretary of State Pick

Trump intends to nominate Rex Tillerson for secretary of state.

"I can think of no one more prepared and no one more dedicated to serve as secretary of state at this critical time in our history," he continued.

Tillerson emerged as a late contender for the job as the nation's top diplomat.

Already, a number of Republican senators have expressed concerns about Tillerson's relationship with Russia, which could pose a challenge for his confirmation in committee votes and on the Senate floor.
