One day after their first successful vote on health care, lawmakers are continuing to go one-by-one through amendments to the bill.

A change passed Thursday by a 61-39 vote will require medical plans to cover "preventive" screening tests like mammograms for women over 40.

However, pro-lifers are concerned the Mikulski amendment-- named after Maryland Sen. Barbara Mikulski-- will categorizes abortion as preventative care, forcing insurance companies to pay for them.

Also Thursday, Senate Democrats rejected an effort by Sen. John McCain, R-Ariz., on a vote of 58-42 to remove Medicare cuts from healthcare legislation.

Senate Minority Leader Mitch McConnell, R-Ky., said the cuts amount to raiding Medicare "to create another new government program."

Democrats say seniors will not lose any guaranteed benefits.

The current bill slashes more than $400 million of Medicare spending to pay for reform.

Still, Democrats are negotiating among themselves to settle disagreements, including objections to the public health insurance option.
