Joe Biden signed the Social Security Fairness Act, expanding benefits for retired Americans, including firefighters, police officers and teachers.

The Social Security Fairness Act repeals two stipulations that have limited payouts for some current and former public employees. But it will also put strain on Social Security Trust Funds, which face a looming insolvency crisis.

President Biden on Sunday signed a measure into law that will boost Social Security payments for nearly 3 million current and former public employees.
