Since 1083 all new government employees had to pay into SS. It includes Congress.
Thank you. Didn’t know that. I do know that when John Cornyn retires - if we are ever fortunate enough to see him do so - he has accumulated retirement funds from at least three different state and federal government jobs he has had. He currently collects from at least one of them in addition to his salary as Senator. Double dipping should not be allowed, particularly when they are paid out of taxpayer funds.
