The House on Friday rejected a resolution to approve the Iran nuclear deal, with the vote underscoring how controversial the accord has been with President Obama’s own party.

While most Democrats voted to approve the nuclear bargain, 25 voted against it, creating a wedge that Republicans hope to use to their advantage in the 2016 elections.

Every Republican voted against the resolution, with the exception of libertarian Rep. Thomas Massie (R-Ky.), who voted "present." The tally was 162-269.

While the failure of the resolution will not prevent the nuclear pact from taking effect, the vote serves as a rebuke of Obama, who has staked his foreign policy legacy on defusing the Iranian threat through diplomacy.

Friday’s vote fell on the anniversary as the Sept. 11, 2001, terrorist attacks, something Republicans were quick to highlight on the House floor as they accused Democrats of backing a “bad deal” that will jeopardize national security and Israel.

"Do not sacrifice the safety, the security and the stability of 300 million Americans for the legacy of one man," implored Rep. Mike Kelly (R-Pa.) as he stood next to a poster of the Twin Towers burning on Sept. 11, 2001.

After the resolution of approval failed, the House passed legislation 247-186 that would prevent Obama from lifting sanctions against Iran. That measure would expire on his successor’s first full day in office in January 2017.
