About 18 Democratic senators and Republicans worked until late Thursday to reduce about $107 billion from a plan which has grown to a $937 billion package to boost the economy, according to a report.

Senate Majority Leader Harry Reid was cautiously optimistic that the senators could have their plan ready by Friday, according to Reuters. If there was a stall in the process he could force a vote by Sunday, he added.

President Barack Obama has been issuing urgent pleas to Congress this week to pass the plan, which will include spending to modernized the nation's infrastructure for such projects as rebuilding roads and bridges. Other aspects of the plan include tax breaks for individuals and businesses.
