WASHINGTON — A Congress riven along party lines approved a landmark $1.9 trillion COVID-19 relief bill Wednesday, as President Joe Biden and Democrats claimed a triumph on a bill that marshals the government's spending might against twin pandemic and economic crises that have upended a nation.

The House gave final congressional approval to the sweeping package by a near party line 220-211 vote precisely seven weeks after Biden entered the White House and four days after the Senate passed the bill without a single Republican vote. GOP lawmakers opposed the package as bloated, crammed with liberal policies and heedless of signs the crises are easing.

Most noticeable to many Americans are provisions to provide up to $1,400 direct payments this year to most adults and extend $300 per week emergency unemployment benefits into early September.

"Today we have a decision to make of tremendous consequence," said House Speaker Nancy Pelosi, D-Calif., "a decision that will make a difference for millions of Americans, saving lives and livelihoods."

A dominant feature of the 628-page bill is initiatives making it one of the biggest federal efforts in years to assist lower- and middle-income families. Included are expanded tax credits over the next year for children, child care and family leave — some of them credits that Democrats have signaled they'd like to make permanent — plus spending for renters, feeding programs and people's utility bills.

Besides the direct payments and jobless-benefit extension, the measure has hundreds of billions for COVID-19 vaccines and treatments, schools, state and local governments and ailing industries from airlines to concert halls. There is aid for farmers of color, pension systems and student borrowers, and subsidies for consumers buying health insurance and states expanding Medicaid coverage for lower earners.

The relief bill now awaits Biden's signature before it becomes law.
