The U.S. Congress early on Saturday passed a measure to boost Social Security retirement payments to some retirees who draw public pensions - such as former police and firefighters - which critics warned will further weaken the program's finances. The Senate in a 76-20 bipartisan vote shortly after midnight approved the Social Security Fairness Act, which would repeal two-decades-old provisions that can reduce benefits for people who also receive a pension. The House of Representatives last month approved the bill in a 327-75 vote, which means that Senate approval sends it to Democratic President Joe Biden to sign into law.
