WASHINGTON (AP) — With the clock ticking to a partial government shutdown at midnight, the top Democrat in the Senate said Friday that the White House and Republicans have agreed on a spending cut of $38 billion but a that fight over federal dollars for Planned Parenthood is blocking a deal. Senate Majority Leader Harry Reid told reporters he was cautiously optimistic after late night talks at the White House, but the budget dispute also has become a moving target. Reid said that in addition to agreeing on the spending cut, negotiators had worked out policy disputes that involve environmental protection, implementing President Barack Obama's health care law and regulating the Internet.
