Washington (CNN) – Sen. Ben Nelson tells CNN he has received a compromise proposal on abortion restrictions that look "better than what's in the bill," but that he has to review it, and send it back to anti-abortion interest groups in his home state of Nebraska.
The compromise proposal was devised by Sen. Bob Casey, D-Penn, another anti-abortion Democrat who has been trying to help Democratic leaders and Nelson negotiate a compromise to win his support for health care.
A Democratic leadership aide would say only that Senate Majority Leader Harry Reid, Nelson and others have been "going back and forth" with ideas on how to find common ground on this vexing issue for several days.
Nelson - whose vote is likely crucial to pass the Democratic health care reform bill - has said he believes the abortion restrictions in the Senate bill are too weak, and has threatened to vote against the plan if it isn't changed. His amendment to adopt the strict prohibitions passed by the House was defeated.
