The Senate voted early Saturday morning to repeal two laws that prevent many public employees from receiving Social Security, a move that is expected to weigh on the overall solvency of the Social Security system.

The popular measure gives full benefits to millions of people who currently receive them at a reduced level. Critics warn the $196 billion cost will speed up the program’s insolvency.

The Windfall Elimination Provision (WEP) reduces Social Security for those who earn “non-covered” pension income their jobs, which are typically public sector roles, that didn’t contribute Social Security payroll taxes. Those workers can lose up to half the pension amount.
