Here's Who's Suing the U.S. Treasury Over Stimulus Checks
Under the Coronavirus Aid, Relief, and Economic Security (CARES) Act, stimulus payments of $1,200 per adult and $500 per dependent child are being made available to most individuals and families.
However, families with mixed immigration status were excluded from receiving COVID-19 stimulus payments due to a requirement in the bill that the money go only to taxpayers who file returns with Social Security numbers. In particular, with joint returns, both spouses have to have a Social Security number.
Those who were left out have now turned to the federal courts, arguing it's unconstitutional to deprive them of the funds every other American received.
