The U.S. Senate on Wednesday cleared the way for lawmakers to decide on Thursday whether to confirm Sylvia Mathews Burwell as President Barack Obama's new health secretary. Senators voted 67-28 to approve a procedural measure limiting debate on Burwell's nomination to no more than 30 hours, allowing a final confirmation vote to move forward sometime on Thursday. Senate approval is widely expected. A confirmation vote allowing Burwell to take over implementation of Obamacare from departing U.S. Health and Human Services Secretary Kathleen Sebelius could help open a new chapter for Obama's healthcare law just five months before November's midterm congressional elections.
