WASHINGTON — A sweeping bipartisan majority in the Senate on Wednesday rejected President Obama’s veto of legislation that would allow families of those killed in the Sept. 11, 2001, terrorist attacks to sue Saudi Arabia for any role in the plot, all but assuring that Mr. Obama would suffer the first override vote of his presidency.
The vote was 97 to 1, with only Senator Harry Reid, Democrat of Nevada, siding with the president.
With the House nearly certain to follow the Senate later on Wednesday, the 9/11 bill will become law in a remarkable yet complicated bipartisan rebuke. Still, the measure itself remains contentious, and even some of those who cast a vote against Mr. Obama conceded that they did not fully support it.
Mr. Obama’s greatest allies on Capitol Hill, who have labored for nearly eight years to stop most bills he opposes from even crossing his desk, turned against him, joining Republicans in the remonstrance.
