A bill pushed by Ryan, whose family fled famine-ravaged Ireland in 1851, could provide Irish nationals with thousands of additional U.S. work visas each year.

The legislation cleared the House Nov. 28 on an uncontested voice vote and is increasingly likely to clear the Senate next week, a GOP aide told POLITICO.

But the measure has stirred opposition from the alt-right publication Breitbart, which dubbed the visa program “amnesty for Irish lobbies“ and said it would take jobs away from U.S. college graduates.
