Meanwhile, millions of California residents may be in line to get a fourth check via a new effort from Governor Gavin Newsom. His plan would send $600 stimulus checks to state residents under a multibillion-dollar spending plan he introduced earlier this month, with about two-thirds of Californians possibly receiving a stimulus payment under his proposal. The letter from the U.S. senators doesn't specify how large are the payments they are seeking, but a separate effort from Democratic lawmakers in January pushed for $2,000 monthly checks until the pandemic ends. Instead, the American Rescue Plan authorized $1,400 for each eligible adult and dependent.
