The Iran nuclear deal has survived a key vote in the Senate, in a victory for President Barack Obama.

Democrats held together to block a resolution of disapproval against the deal. The vote was 58-42 in favor of proceeding, but 60 votes were needed for the resolution to advance to a final vote.

The outcome means the disapproval resolution will not reach Obama's desk, and the nuclear deal will move forward unchecked by Congress.

Senate Republicans are vowing they'll keep on fighting. House Republicans also are still maneuvering to find a way to stop the international agreement to curb Iran's nuclear program. But those efforts seem unlikely to produce results.

For Obama it's an unlikely victory on the hard-won accord over unanimous Republican opposition.
