WASHINGTON (AP) — Moving with lightning speed, Congress and the White House agreed Wednesday on a compromise $790 billion economic stimulus bill designed to create million jobs in a nation reeling from recession. President Barack Obama could sign the measure within days. “More than one-third of this bill is dedicated to providing tax relief for middle-class families, cutting taxes for 95 percent of American workers,” said Senate Majority Leader Harry Reid at a Capitol news conference where he was joined by moderates from both parties whose support is essential for the legislation’s final passage. Obama estimated 3.5 million in his own celebration of the agreement. He said it would “get our economy back on track.”
