President Barack Obama nominated White House budget office director Sylvia Matthews Burwell to be the next Department of Health and Human Services secretary, following the resignation of Kathleen Sebelius Friday morning.

Sebelius leaves the administration after the tumultuous launch of the Affordable Care Act exchanges last fall.

Despite calls for her ouster from Republicans at the time, she stayed on until the enrollment period ended March 31st.

After singing Sebelius' praises, Obama introduced Burwell saying, "She's a proven manager who's demonstrated her ability to field great teams, forge strong relationships, and deliver excellent results at the highest levels and she's done both in the public and private sectors."

The Senate must approve Burwell's nomination before she can take the helm at the agency.
