WASHINGTON — Approval of a bipartisan bill that would allow families of Sept. 11 victims to sue the government of Saudi Arabia puts Congress on a collision course with President Barack Obama on the eve of the 15th anniversary of the attacks.

The House passed the legislation Friday by voice vote, about four months after the measure cleared the Senate despite vehement objections from Saudi Arabia. Fifteen of the 19 hijackers were Saudi nationals.

The White House has signaled Obama would veto the legislation over the potential for the measure to backfire. The Obama administration cautions that if U.S. citizens can take the Saudis to court, then a foreign country could in turn sue the United States. There also is apprehension the bill would undermine a long-standing relationship with a critical U.S. ally in the Middle East.

Votes from two-thirds of the members in the House and Senate would be needed to override a veto.

There was no immediate comment from Saudi Arabia, which was preparing for the annual hajj pilgrimage beginning Saturday.
