WASHINGTON (Reuters) – The U.S. Senate on Friday threw its weight behind the annual National Defense Authorization Act, or NDAA, a $740 billion bill setting policy for the Department of Defense, passing the bill with a margin large enough to overcome President Donald Trump’s promised veto.

The Republican-controlled Senate backed the bill by 84 to 13, more than the two-thirds majority needed in the 100-member chamber to override a veto.

The Democratic-led House of Representatives backed the NDAA by 335 to 78 earlier this week, also more than the two-thirds majority needed.

Backers hope strong bipartisan support will prompt Trump to reconsider his threat to veto the annual bill, which sets policy for the U.S. military and has become law for 59 straight years.

The White House said earlier on Friday that Trump’s position had not changed. The president will have 10 days – minus Sundays – to issue a veto, sign it or allow it to become law without his signature.

Trump has threatened to veto the fiscal 2021 NDAA because of a provision to remove the names of Confederate generals from military bases.

He also objects because it does not repeal Section 230 of the Communications Decency Act, which protects technology companies like Alphabet Inc’s Google, Twitter Inc and Facebook Inc from liability for what appears on their platforms, although that is not related to the military.

Trump also objects to some provisions in the legislation that could slow plans to withdraw troops from Afghanistan and Germany.
