President-elect Donald Trump's pick for secretary of state, Rex Tillerson, begins his confirmation hearings Wednesday.

Tillerson, the former ExxonMobil chief executive officer, is expected to face a tough hearing before the Senate Foreign Relations Committee, as members from both sides of the aisle seek to figure out specific foreign policy points under a Trump administration.

Tillerson will also face questions about his ties to Russia and his stance on the apparent Russian involvement in the U.S. election.

His duties at the energy giant are also expected to come under scrutiny during the confirmation hearings.
