Four of President-elect Donald Trump's Cabinet nominations face confirmation hearings Wednesday, all starting at 10 a.m. Eastern time. They are:

Nikki Haley, U.N. ambassador
Scott Pruitt, EPA administrator
Tom Price, Health and Human Services Secretary
Wilbur Ross, Secretary of Commerce

Price has come under fire after reports that he wrote legislation as a Congressman that helped companies he had stock in. Trump has said his plan to replace Obamacare is dependent on Price's confirmation.

Pruitt is a close ally of the fossil fuel industry, and he doubts that humans have caused global warming, a first for an EPA head. Sen. Bernie Sanders said he would "vigorously oppose" his nomination.

Environmentalists have called Pruitt a "nightmare."

Haley, the governor of South Carolina, was an outspoken Trump critic before he was nominated as the Republican candidate. She is the second Asian-American governor in U.S. history.
