WASHINGTON (AP) — House Speaker Nancy Pelosi pressed ahead Tuesday with the next coronavirus  aid, a sweeping package that is expected to be unveiled soon even as the House stays closed while the Senate reopens in the pandemic.

Key to any plan to reopen the economy, Democrats say, is robust testing. They are also expected to propose another round of direct cash aid for anxious Americans, funds for states to prevent layoffs and more money to shore up businesses in the stay-home economy. Pelosi had indicated more than $800 billion could be needed, but her office declined to confirm a final figure Tuesday.

"We still don't have a national testing strategy that is adequate," Senate Democratic leader Chuck Schumer said. He called it embarrassing. "It's life and death."

The contours of the next package are taking shape despite Republican resistance to more spending and a deepening debate over how best to confront the deadly pandemic and its economic devastation.

Senate Majority Leader Mitch McConnell said Tuesday it's time to push "pause" on more aid.

President Donald Trump is encouraging states to reopen and Republicans hope the gradual comeback will kick-start the economy, reducing the pressure for more pricey aid.

"Now it's time to go back to work," Trump said at the White House.

Under strict social distancing guidelines, the Senate reconvened Monday for the first time since March, while the House is staying away due to the health risks. The Washington area remains a virus hot spot under stay-home rules.

McConnell has focused the chamber's workload on confirming Trump's nominees. The GOP leader insists that any new aid package must include liability protections for the hospitals, health care providers and businesses that are operating and reopening in the pandemic. He said Tuesday he wants to prevent "an epidemic of lawsuits."

But the Republican leader also signaled an interest in beefed up virus testing strategies as central to the nation's ability to take steps "back toward normalcy."

"Testing, tracking, treatments," McConnell said from the Senate floor.

By reconvening this week, Senate Republicans are trying to set the terms of debate, frustrated that Pelosi was able to fill up earlier aid bills with Democratic priorities. They're reluctant to unleash federal funds beyond the nearly $3 trillion Congress already approved in virus relief and hope Trump's push to re-open will reduce the need for more aid.

"I just don't think we need to act as quite urgently as we did last time," Sen. John Cornyn, R-Texas told reporters at the Capitol.

The No. 2 Republican, Sen. John Thune of South Dakota, said Washington had already "flooded the zone" with virus relief and should assess "what's working and what's not."

Senators returned to a changed place with new guidelines, including the recommendation that senators wear masks, though not all of them were complying.

Sen. Rand Paul, R-Ky., who tested positive for the virus in March, asserted he no longer needs to cover his face because he has "immunity" — even though health officials warn there is no guarantee that infected people can't contract the virus again.

It's not just lawmakers at risk. Reopening part of Capitol Hill poses health risks for the cooks, cleaners, police officers and other workers who keep the Capitol complex functioning.

Senators were encouraged to keep their distance and leave most staff at home, though Republican senators gathered as a large group for their traditional luncheon. Public access to the Capitol is limited, including at public hearings. The Capitol itself remains closed to visitors and tours.

Democrats are eyeing the new aid package as states and cities seek as much as $1 trillion to prevent local layoffs and keep paying nurses, police, firefighters and other front-line workers as local revenues tank during the stay-home shutdown.

Pelosi outlined the governors' requests for $500 billion, with the counties and cities seeking as much as $300 billion, which she has said could be spread out over the next several years. On a private conference call with House Democrats on Monday, she also discussed a "paycheck guarantee" for the newly jobless.

Several House committee chairmen outlined the provisions expected in the upcoming bill, according to a statement from the Democratic caucus after the private call.

Ways and Means Committee Chairman Richard Neal discussed another round of additional direct cash payments for families and extending unemployment insurance. Rep. Maxine Waters, D-Ca., chair of the Financial Services Committee, focused on helping homeowners, renters and small landlords make rent and mortgage payments, the statement said. Energy and Commerce Chairman Frank Pallone spoke about investing in virus testing and contact tracing.

Trump said any new package must have a payroll-tax holiday.

But Republicans are divided on that approach, with some questioning whether it helps the 30 million jobless Americans.

"I've never thought that really would be very effective," Sen. Susan Collins, R-Maine. She said she's working with a bipartisan, bicameral group on a state and local aid package.

In the Senate, McConnell has loaded up the schedule with consideration of Trump's nominees, including a hearing Tuesday on John Ratcliffe, the Texas Republican congressman who is Trump's choice to lead the Office of the Director of National Intelligence.
