"Evicting millions of people during a pandemic would be a moral outrage," she tweeted Thursday. "Cancel rent and mortgage payments now."
Omar linked to a CNN article warning of a potential "huge wave of evictions" in January.
Lockdowns have led to millions of job losses and a financial strain that left Americans struggling to pay their bills. Although the federal government passed a massive relief package earlier this year, Congress and the White House have struggled to compromise on additional benefits.
Meanwhile, U.S. virus cases are increasing, prompting additional restrictions in places like New York City, which just announced it would once again close its public schools.
In September, the Pew Research Center reported that 1 in 4 U.S. adults had trouble paying their bills during the first six months of the crisis. Overall, about 16% of adults said they had problems paying rent or their mortgage.
Compared to other income groups, lower-income Americans saw a significantly higher proportion of individuals who had trouble paying bills (46%), had problems paying rent or mortgage (32%), received food from a "food bank/organization" (35%), and used money from their savings or retirment to pay their bills (44%).
Rep. Alexandria Ocasio-Cortez, D-N.Y., came under fire Thursday when she argued that the federal government should pay people to stay home.
Omar similarly tweeted: "To get the virus under control, we need to pay people to stay home."
