WASHINGTON (AP) -- Senate Democrats are planning to add a few things to a bipartisan 150 billion-dollar economic stimulus package.

Senior Senate aides in both parties say the Senate is planning to draft its own measure to add rebates for senior citizens living off Social Security and an extension of unemployment benefits.

Adding to the plan would be in direct defiance with White House wishes, as President Bush has called on Congress to quickly adopt the original plan. Bush has said additional spending measures could derail the deal.

The House is planning to vote tomorrow on the White House-backed package that would send rebates of up to $600 to most income earners.
