Democratic senators voice concerns about healthcare law rollout

WASHINGTON — Democratic senators, at a caucus meeting with White House officials, expressed concerns on Thursday about how the Obama administration was carrying out the health care law they adopted three years ago. Democrats in both houses of Congress said some members of their party were getting nervous that they could pay a political price if the rollout of the law was messy or if premiums went up significantly. President Obama's new chief of staff, Denis R. McDonough, fielded questions on the issue for more than an hour at a lunch with Democratic senators.
