By LISA MASCARO, DARLENE SUPERVILLE and ALAN FRAM WASHINGTON (AP) — A deal within reach, President Joe Biden and Congress’ top Democrats edged close to sealing their giant domestic legislation Friday, though the day’s informal deadline appeared to slip as they worked to scale back the measure and determine how to pay for it. Negotiations were expected to continue into the weekend, all sides indicating just a few issues remained unsettled in the sweeping package of social services and climate change strategies. Biden met at the White House Friday with House Speaker Nancy Pelosi, and Senate Majority Leader Chuck Schumer joined by video call from from New York, trying to shore up details.
