What exactly is in the contentious $2 trillion stimulus package being debated in the U.S. Senate? The emerging rescue package is expected to provide health care and economic aid amid the widening coronavirus outbreak and national shutdown.

»COMPLETE COVERAGE: CORONAVIRUS

The details were still being worked out Monday as congressional leaders and the White House continue negotiating the nearly $2 trillion package. These are the highlights so far:

One-time checks to Americans

The measure would provide a quick, one-time stipend of about $1,200 per individual, $2,400 for couples and $3,000 for a family of four. The money would cut off at higher income levels.

Paycheck support

An estimated $350 billion would be provided for small businesses to keep making payroll. Companies with 500 or fewer employees could tap up to $10 million each in forgivable small business loans to keep paychecks flowing. The program would provide eight weeks of assistance through federally guaranteed loans to qualifying employers who maintain payroll; if they do, other costs such as mortgage interest, rent and utilities would be forgiven.

Unemployment expansion 

Establishes a new, much more generous unemployment benefit by adding $600 per week to normal state benefits for up to four months and provides an additional 13 weeks of benefits to 39 weeks of regular unemployment insurance through the end of 2020 if they are sidelined by the outbreak. The coverage would be retroactive to Jan. 27. Extends coverage to “gig” workers and independent contractors.

Emergency funding, public health

The bill includes an additional $242 billion in additional emergency appropriations to fight the virus and shore up for safety net programs. That includes money for food stamps, child nutrition, hospitals, the Centers for Disease Control and public health and transportation agencies. The figure went significantly higher during talks last weekend.

The measure includes $15.6 billion to augment the food stamp program, which helps feed about 40 million low-income people per year. Its annual budget is about $70 billion. A bipartisan package is likely to provide far more.

Industry aid

The initial GOP plan called for $208 billion in loans to larger businesses such as airlines, which would have to be repaid. A subsequent version released last weekend called for $500 billion. Leaders are still negotiating the final number and how the money would be provided by the administration and safeguards to prevent abuses. The proposal also delays payroll tax payments by employers. They would be able to defer payment of their 2020 payroll taxes until 2021 and 2022.

Aid to states 

Republicans and the administration have resisted demands by Democrats and governors for aid to the states, whose governors have requested $150 billion to shore up budgets strained by large new costs and plummeting tax revenues. Negotiations are likely to produce a compromise.
