US Speaker of the House Nancy Pelosi (L) and Senate Democratic Leader Chuck Schumer (R) hold a press conference on Capitol Hill in Washington, DC, May 22, 2019, following a meeting with US President Donald Trump at the White House.

The top Democrats in Congress pushed Wednesday for an "interim" emergency coronavirus bill to include at least $500 billion in relief for small businesses, hospitals, states and food assistance programs.

By the afternoon, House Democrats indicated they will try to pass legislation that includes less money specifically for an existing loan program for small companies than the Trump administration has requested.

In a joint statement Wednesday morning, House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer said they supported another $250 billion in loans to small companies. A spokesperson for Pelosi later clarified that House Democrats want to put $125 billion into the so-called Paycheck Protection Program — a $350 billion pool of loans approved as part of the $2 trillion emergency package passed last month. Another $125 billion would go to community-based lenders and Small Business Administration disaster assistance loans and grants.

Senate Majority Leader Mitch McConnell aims to pass $250 billion in funding for the existing program through the Senate on Thursday. On a call with House Democrats, Pelosi said she hopes to pass her stopgap bill on Friday.

Meanwhile, Democrats want the stopgap legislation to go further as the coronavirus pandemic rips across the country, stretching health-care resources and state budgets and shutting down schools and businesses. Pelosi and Schumer also called for:

$100 billion to bolster hospitals and community health centers, with funds going toward the production of coronavirus tests and protective medical equipment

$150 billion for state and local governments (some officials such as New York Gov. Andrew Cuomo, who is managing the epicenter of the U.S. outbreak, said the last congressional bill did not do enough for states battling coronavirus)

A 15% increase to the maximum Supplemental Nutrition Assistance Program benefit

It is unclear if the GOP-controlled Senate and Democratic-held House will go through with passing divergent legislation, or if they can agree on a compromise before the planned Senate vote Thursday.

The Democratic leaders described the "interim" bill as separate from one they aim to pass to expand the provisions of the $2 trillion aid package. The federal government has only started to implement the law, the largest emergency spending measure in U.S. history.

"After we pass this interim emergency legislation, Congress will move to pass a CARES 2 Act that will extend and expand the bipartisan CARES Act to meet the needs of the American people," Pelosi and Schumer said. "CARES 2 must provide transformational relief as the American people weather this assault on their lives and livelihoods."
