Democrats controlling Congress ratcheted up expectations Tuesday for additional legislation to jump-start the dragging economy. "We will be proceeding with another stimulus package," House Speaker Nancy Pelosi, D-Calif., said after meeting with several economists. Pelosi said that recently issued tax rebate payments of $600 to individuals and $1,200 for married couples have helped the economy but that more is necessary to offset the drag of higher gasoline prices and other costs. But President Bush cautioned in a White House press conference that lawmakers should "wait for the stimulus package to fully kick in" before passing another.

The Democratic effort is still in its formative stages, but most of the proposals mentioned by Democrats were rejected by Bush during negotiations that produced the earlier stimulus measure. A new package probably won't be acted on before Congress returns in September from its annual summer vacation.

New legislation could include: additional tax rebates, heating and air conditioning subsidies for the poor, infrastructure projects, higher food stamp payments and aid to the states.

Pelosi told reporters that she "would hope that (tax rebates) would be part of any package" but that some of the Democratic elements need to be attached. Pelosi said later Tuesday that she hopes proposals such as boosting food stamps and home energy subsidies would have more GOP support now, considering the sharp spikes in gasoline and food prices.
