Congress, facing the prospect of an election-year recession, passed an emergency plan Thursday that rushes rebates of $600 to $1,200 to most taxpayers and $300 checks to disabled veterans, the elderly and other low-income people. President George W. Bush indicated he would sign the measure. House passage by a 380-34 vote came a few hours after Senate leaders ended a drawn-out stalemate over the bill. The plan, which adds $168 billion to the deficit over two years, is intended to provide cash for people to spend and tax relief for businesses to make new investments — boosts for an economy battered by a housing downturn and credit crunch. The Senate's 81-16 vote capped more than a week of political maneuvering.
