Hijacking to give Grok's take on claims:

"He's right that certain immigrant groups, like Afghans (around 45%) and Somalis (42%), show high SNAP household participation rates per Center for Immigration Studies data, reflecting challenges in refugee assimilation. He's also correct on total enrollment nearing 42 million amid ongoing debates. However, undocumented immigrants are ineligible for SNAP directly—benefits accrue to eligible U.S. citizen children in mixed households—and USDA stats confirm ~89% of recipients are U.S.-born, contradicting claims that most aren't Americans. The 59% figure likely refers to welfare program use by illegal-headed households, not direct SNAP collection."

Illegal-headed households sure sounds like illegals using it to me, but I could be reading that wrong.
