WASHINGTON (AP) - President Barack Obama's Democratic allies in Congress have agreed to let his signature $400 tax cut for most workers expire after next year but are moving to give him a better chance at passing his health care bill. Senate Majority Leader Harry Reid, D-Nev., said Friday that most issues have been resolved in trying to combine different House and Senate approaches into one budget bill. That measure will set the rules on how Congress considers Obama's agenda for the rest of the year.
