From Andrea Mitchell writing at NBC News:
Donald Trump is expected to nominate Exxon Mobil CEO Rex Tillerson as his secretary of state, two sources close to the transition process told NBC News on Saturday.
Tillerson, 64, became president of the Texas-based oil company in 2004 and has a close business relationship with Russian President Vladimir Putin. He has spent his entire career at the company now known as Exxon Mobil.
Tillerson will be paired with former U.N. Ambassador John Bolton as his deputy secretary of state for day-to-day management of the department, one source added.
