WASHINGTON — Frustrated negotiators of a massive coronavirus relief bill face heightened pressure with Thursday’s brutal economic news and the rapidly approaching lapse in a $600 per-week expanded jobless benefit that has helped prop up consumer demand. Talks are at a standstill with few reasons for optimism despite sweeping agreement among Washington’s top power players that Congress must pass further relief in coming days and weeks. President Donald Trump is eager for another COVID relief package, also a priority for GOP allies like Senate Majority Leader Mitch McConnell, as well as House Speaker Nancy Pelosi and top Senate Democrat Chuck Schumer.
