Sen. Tom Harkin (D-Iowa) said Tuesday he has lifted his hold on one of President Obama's top healthcare nominees. Harkin had placed a hold on the nomination of Marilyn Tavenner, whom Obama tapped to lead the agency that oversees Medicare, Medicaid and the implementation of the Affordable Care Act. Harkin was upset about cuts the administration has made to the healthcare law's prevention and public health fund. He reiterated those objections during a floor speech Tuesday but said he would allow Tavenner's nomination to move forward. "I don't know who's advising the president on this, but I think the president is getting bad advice," Harkin said of the prevention fund.
