Senate overwhelmingly overrides Obama's veto

The US Senate yesterday voted overwhelmingly to override Barack Obama's veto of a bill allowing 9/11 victims to sue Saudi Arabia, the first such rebuke of his eight-year presidency.

In a landmark 97-1 vote backing the override, only outgoing Obama ally, Nevada Democrat Harry Reid, voted against it, teeing up a similar vote in the House of Representatives later yesterday.

The rare act of bipartisanship is a severe blow to Obama, who lobbied hard against the bill, known as the Justice Against Sponsors of Terrorism Act (JASTA).

The rebuke marks Obama's last months in office and shows the White House to be much weakened.

Obama has issued 12 vetoes during his presidency. Until now none have been overridden, a rare feat given Republicans' longstanding control of Congress.

His Republican predecessor George W Bush also issued 12 vetoes and four were overriden.

The White House argued the 9/11 bill would undermine the principle of sovereign immunity and open up the United States itself to lawsuits.

Families of 9/11 victims have campaigned for the law -- convinced that the Saudi government had a hand in the attacks that killed almost 3,000 people.

Fifteen of the 19 hijackers were Saudi citizens, but no link to the government has been proven.

The Saudi government denies any links to the plotters. Behind the scenes, Riyadh has been lobbying furiously for the bill to be scrapped.

Declassified documents showed US intelligence had multiple suspicions about links between the Saudi government and the attackers.

A senior Saudi prince reportedly threatened to pull billions of dollars out of US assets if it becomes law, but Saudi officials now distance themselves from that claim.

The US-Saudi relationship had already been strained by Obama's engagement with Saudi's Shia foe Iran and the July release of a secret report on Saudi involvement in the attacks.
