NEW YORK, July 1 (Xinhua) -- The U.S. Senate on Tuesday narrowly passed its version of the Trump administration's tax and spending measure dubbed One Big Beautiful Bill, which is expected to add around 3.3 trillion U.S. dollars of deficit through 2034.

The Republican-controlled Senate passed the bill by 51 to 50 after a marathon voting process that started Monday morning.

Senators spent the past few days reading out and debating the 940-page bill, which was unveiled late Friday.

The legislation includes more spending on border security, defense and energy production, with cuts to healthcare, nutrition programs and electric vehicle subsidies. The bill extends U.S. President Donald Trump's 2017 Tax Cuts and Jobs Act, which is set to expire at the end of 2025.

The mega-bill would add about 3.3 trillion dollars of deficit in the next decade, higher than the 2.8 trillion dollars of deficit in the version passed by the House of Representatives on May 22, according to the latest estimate by the Congressional Budget Office on Sunday.

The House of Representatives needs to approve the revisions to its version of the bill, which was passed on May 22.

Earlier, Trump urged lawmakers to pass the bill before July 4. Enditem
