On Wednesday, the U.S. senator sponsoring a contentious bill to throw out per-country green card limits warned that a particular colleague might object to it when he brought it to the Senate on Thursday.

The colleague, Sen. Dick Durbin (R-IL), did exactly that, according to a Washington, D.C. correspondent for a Kansas newspaper. That makes the third time bill S386 — also spearheaded by Sen. Kamala Harris (D-CA) — has been blocked in the Senate this year.
