Senators Bernie Sanders, Kamala Harris, and Ed Markey will introduce a bill to give Americans an additional $2,000 a month for the duration of the coronavirus crisis.The bill would give $2,000 a month to every American with an income of less than $120,000 for the duration of the crisis, and for three months after, according to a release.Married couples filing jointly would get $4,000, and $2,000 for each child up to three children.The funds would be available to all U.S. residents, including those who had not filed taxes or did not have a social security card.This is a key difference from the $1,200 one-time stimulus provided by the CARES Act.House Democrats proposed a similar bill in April that would give $2,000 a month to U.S. citizens until the emergency was over.Visit Business Insider's
