WASHINGTON – Negotiations on a huge COVID-19 relief bill have taken a modest step forward, though time is running out and Senate Majority Leader Mitch McConnell, President Donald Trump's most powerful Senate ally, is pressing the White House not to move ahead.McConnell told fellow Republicans that he has warned the White House not to divide Republicans by sealing a lopsided $2 trillion relief deal with House Speaker Nancy Pelosi before the election — even as he publicly said he'd slate any such agreement for a vote.Pelosi's office said talks with Treasury Secretary Steven Mnuchin on Tuesday were productive, but other veteran lawmakers said there is still too much work to do and not enough time to do it to enact a relief bill by Election.
