President Biden signed the $1.9 trillion coronavirus relief package on Thursday. The colossal bill, known as the American Rescue Plan, allocates money for vaccines, schools, small businesses and anti-poverty programs such as an expanded child tax credit that will mean new monthly payments to many parents.

The House gave its final approval on Wednesday, after the Senate made changes to the original bill — some to satisfy Senate budget rules and others to gain the support of moderate Democrats.

House Speaker Nancy Pelosi, D-Calif., had urged Republicans to join House Democrats in supporting the bill, but in the end no GOP member voted in favor of it.

Republicans have argued that they were effectively shut out of the process through reconciliation and that the package is too broad, saying only 9% of the funds go directly toward COVID-19 relief. Both House Minority Leader Kevin McCarthy and Senate Minority Leader Mitch McConnell have labeled the bill a Democratic "wish list."

But Democrats counter that the bill takes a holistic look at the entire American economy and how it has been affected by the coronavirus pandemic.

Sen. Angus King, I-Maine, called Republicans' framing of the bill "nonsense."

"There are really two pieces to this bill. One is directly related to the health crisis, but the other, and the larger piece, is related to the economic crisis that the health crisis has created," King told NPR's Rachel Martin on Monday.

"The major pieces of the bill — payments to individuals, extended unemployment, money for states and localities, money for schools — all of those things were in the COVID package that passed last year that all the Republicans voted for. So they were OK then, but they're not OK now, and I frankly can't really figure out that argument."

One much-discussed proposal that didn't make the final cut was an increase in the minimum wage. Progressive Democrats vigorously pursued including a minimum wage hike in this legislation, which would have gradually increased the federal minimum wage to $15 an hour by 2025. But the nonpartisan Senate parliamentarian ruled that including such a provision does not align with the complicated rules over budget bills, so it is not in the final legislation.

Here's a closer look at some of the big-ticket provisions in the Senate-amended bill that Biden has signed.

Direct payments

The bill allocates funds for a third economic impact payment to qualifying Americans.

Individuals earning up to $75,000 and couples earning up to $150,000 will receive the full direct payments of $1,400 per person. Individuals will also receive an additional $1,400 payment for each dependent claimed on their tax returns.

Senate Democrats agreed to lower the income cutoff at which payments phase out from $100,000 to $80,000 for individuals, and from $200,000 to $160,000 for couples filing jointly, following demands from moderate Democrats.

Unemployment benefits

Under the Senate version that Biden signed, federal unemployment insurance payments will remain at $300 per week — down from $400 per week in the earlier package passed by the House. The benefits will extend through Sept. 6. The Senate's bill makes the first $10,200 in unemployment payments nontaxable for households with incomes under $150,000.

Child tax credit

The legislation will temporarily expand the child tax credit, increasing the amount to $3,000 for children ages 6 to 17 and $3,600 for children under age 6.

The amount is gradually reduced for couples earning over $150,000 and individuals earning over $75,000 per year. Families eligible for the full credit will get payments of up to $300 per child per month from July through the end of the year.

Congressional Democrats and the White House may want to figure out how to make the credit permanent.

Paycheck Protection Program

The bill includes $7.25 billion in new money for the small-business loan program known as PPP and will allow more nonprofits to apply, including groups that engage in advocacy and some limited lobbying. It also allows larger nonprofits to be eligible.

Education

There are over $128 billion in grants to state educational agencies, with 90% allocated to local educational agencies, plus$39 billion in grants to higher education institutions.Nearly $15 billion in funds are directed to the Child Care & Development Block Grant program to help support child care facilities, particularly in high-need areas.

The Senate version signed by Biden added a provision to make any student loan forgiveness passed between Dec. 31, 2020, and Jan. 1, 2026, tax-free — rather than having the forgiven debt be treated as taxable income.

Support for low-income families

The legislation includes $4.5 billion for the Low Income Home Energy Assistance Program, known as LIHEAP, to help families with home heating and cooling costs. One provision will give the agriculture secretary the authority and funding to temporarily boost the value of cash vouchers for the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) up to $35 per month for women and children for a four-month period during the pandemic.

There is $1.4 billion in funding for programs authorized under the Older Americans Act, including support for nutrition programs, community-based support programs and the National Family Caregiver Support Program.

The bill provides $37 million to the Commodity Supplemental Food Program for low-income seniors.

Public health

The Centers for Disease Control and Prevention is set to receive $7.5 billion to track, administer and distribute COVID-19 vaccines. Another $46 billion will go toward diagnosing and tracing coronavirus infections, and $2 billion will go toward buying and distributing various testing supplies and personal protective equipment.

Industry support

There's a variety of provisions in the legislation to offer support to different industries. The Small Business Administration will get $25 billion for a new grant program for "restaurants and other food and drinking establishments." Grants will be up to $10 million per entity and $5 million per physical location, with a maximum of 20 locations. The legislation sets aside $5 billion of the total money to be targeted to businesses with less than $500,000 in revenue in 2019.The legislation includes another $1.25 billion for the Small Business Administration's Shuttered Venue Operators Grant program.

To support the transportation sector, the legislation allocates nearly $30 billion for transit costs, including payroll and personal protective equipment; $8 billion for airports; $3 billion for a temporary payroll support program to help support the aerospace manufacturing industry; and $1.5 billion to recall and pay Amtrak employees who were furloughed because of the pandemic and to restore various daily routes. Another $15 billion will also be allocated to support workers in the airline industry.

Rental assistance

There is $25 billion for emergency rental assistance, including $5 billion for emergency housing vouchers for people experiencing homelessness, survivors of domestic violence and victims of human trafficking.
