Why it matters: The previous three attempts by Sen. Bob Menendez (D-N.J.) and Sen. Ted Cruz (R-Texas) to pass the resolution were blocked by Republican senators at the request of the White House, which feared that its passage would infuriate the Turkish government during a tense period of U.S.-Turkey relations.

Sens. Lindsey Graham (R-S.C.), David Perdue (R-Ga.) and Kevin Cramer (R-N.D.) previously objected to the resolution, but indicated that they were not willing to do so again.

Mendendez, who has championed the cause since arriving in the Senate in 2006, became emotional on the Senate floor as he spoke following the passage of the resolution.
