The Senate overrode President Trump's veto of the National Defense Authorization Act, the $740 billion defense policy bill. This veto, in the waning days of Mr. Trump's presidency, marked the first time Congress has voted to override him.
The final vote tally was 81 to 13, with a two-thirds vote required to overturn the veto. The bill had previously passed in the Senate 84-13 earlier this month, and the House has already voted to override Mr. Trump's veto.
Mr. Trump tweeted after the vote that Senate Republicans had "missed a big opportunity to get rid of Section 230", one of the portions of the bill he had objected to. Mr. Trump wanted to repeal the social media liability shield, but several members of Congress, including some Republicans, argued that the repeal of Section 230 of the Communications Decency Act was not relevant to national security.
Mr. Trump also vetoed the NDAA because of a provision on renaming bases honoring Confederate officials.
