CNN – White House chief of staff Mark Meadows said Sunday that the administration has been engaged in discussions on the next stimulus bill for the past week, but negotiations will start "in earnest" Monday on Capitol Hill. "As we've started to engage with our Senate and House colleagues up on Capitol Hill, those will start in earnest starting tomorrow, Monday," Meadows said in an interview on Fox News. Senate Majority Leader Mitch McConnell and House Minority Leader Kevin McCarthy will meet with President Donald Trump and Treasury Secretary Steven Mnuchin "to actually start to fine tune it," Meadows added. "Whether it's a payroll tax deduction, whether it's making sure that unemployment benefits continue without a disincentive to return to work," he said. The issue of continuing unemployment benefits has been a sticking point for Democrats in negotiations.
