Congress on Wednesday voted overwhelmingly to override President Obama’s veto of legislation that would allow 9/11 victims’ families to sue the Saudi Arabian government over its alleged support for the terrorists who carried out the attacks. It is the first time during the Obama administration that Congress has voted to override a veto. The votes in the House and Senate amounted to a sweeping, bipartisan rejection of the White House’s argument that the legislation poses a national security threat because it could expose U.S. officials to similar lawsuits abroad.
