WASHINGTON (AP) — Senate Democrats are scrambling to rewrite portions of President Barack Obama's jobs bill as they seek elusive party unity around the measure, even as Obama tries to pin the blame on Republicans for Congress' failure to act.

Officials say Democrats are moving to jettison provisions that Obama recommended to pay for the bill and substitute a tax increase on millionaires. It could get support from Democrats who oppose Obama's plans for higher taxes for oil and gas companies and for couples making more than $250,000 a year.

The White House says it's open to such changes. The officials spoke on condition of anonymity to discuss the developments.

Senate Majority Leader Harry Reid predicts near-unanimous Democratic support when the bill is considered this month. In the House, majority Republicans remain opposed.
