Privacy advocates from the Electronic Frontier Foundation (EFF) and the American Civil Liberties Union (ACLU) point out that the bill voted today also enhances the USA government's spy powers by expanding its dragnet data collection.
Trump later changed his tune, saying the bill was about "foreign surveillance of foreign bad guys" and urging support.
House Intelligence Committee member Rep. Jim Himes, D-Conn., blasted Trump's earlier tweet as "truly incredible", highlighting the disconnect with his own White House team. About 90 minutes later he reversed course.
In his first tweet, Trump linked FISA, which his White House supports, to the dossier that alleges his campaign had ties to Russian Federation, catching aides and Capitol Hill officials off guard and drawing the ire of his critics for misconstruing what the program actually does.
Prior to Thursday's vote, confusion surrounded the official White House position on 702 after a tweet from President Trump contradicted an official statement released Wednesday evening opposing Amash's amendment. Trump hints in his first tweet that it may have been used under the Obama administration to spy on his campaign.
Why did Trump's tweets start a Congressional panic?
Speaker of the House Paul Ryan (R-WI) argued that the amendment would lead to the country "flying blind" in its search for terrorism suspects. Later, House Majority Leader Kevin McCarthy (R-Calif.) alerted the GOP conference that the president had tweeted again, calming lawmakers' nerves.
The dossier examines ties between Russian Federation and Trump and his aides.
Some Republicans and Democrats had unsuccessfully proposed an amendment that would have required a warrant to scrutinise United States citizens' data. Though FISA is supposed to be used for snooping on foreign targets, it has been brought to bear against Americans and used for domestic crime cases, secretly and without warrants.
The House voted Thursday morning to approve a bill that renews the National Security Agency's warrantless surveillance program, known as Section 702 of the Foreign Intelligence Surveillance Act, with a few small changes.
Section 702 is due to expire next week, though intelligence officials say it could continue until April.
On Thursday, the House of Representatives converged and voted to push the warrantless surveillance program by the National Security Agency by six years. But she added, "The president doesn't believe Americans' rights or liberties should be abused, but he certainly believes Americans should be protected".
