I'm a UK Citizen and even I know this one to be [censored].
"No one — whether he be a citizen, immigrant, or illegal alien — is eligible to collect Social Security benefits unless he (or someone else, such as a parent or spouse) has paid into the system. Someone has confused Social Security itself with Supplemental Security Income (SSI) — the latter is a federal welfare program "designed to help aged, blind, and disabled people, who have little or no income" by providing "cash to meet basic needs for food, clothing, and shelter." Immigrants can qualify for SSI benefits under certain conditions, but SSI is financed by general revenues and not Social Security taxes. SSI was not enacted by the administration of President Jimmy Carter (a Democrat); it was created and signed into law in 1972, during the administration of President Richard Nixon (a Republican)." - Snopes

Honestly, politics aside, does no-one fact check any more?
