The Senate unanimously passed legislation Thursday that would extend sanctions on Iran for 10 years, a move many supported as a way to ensure the U.S. maintains its leverage over Iran in light of questions about its implementation of the Iran nuclear agreement.

The 99-0 Senate vote sends it along to the president’s desk for his signature. The vote came after the House overwhelmingly approved the measure, known as the Iran Sanctions Extension Act, two weeks ago in a 419-1 vote.
