US President Donald Trump.

U.S President Donald Trump on Friday signed into law a bill renewing the National Security Agency (NSA)’s warrantless internet surveillance programme.

“Just signed 702 Bill to reauthorize foreign intelligence collection,” Trump tweeted, referring to legislation passed by the U.S. Congress that extends Section 702 of the Foreign Intelligence Surveillance Act (FISA).

The law renews for six years and with minimal changes the NSA’s programme, which collects information from foreigners overseas but incidentally gathers an unknown amount of communications belonging to Americans.

Under the law, the NSA is allowed to eavesdrop on vast amounts of digital communications from foreigners living outside the United States via U.S. companies like Facebook Inc, Verizon Communications Inc and Alphabet Inc’s Google.

Privacy advocates say the law allows the NSA and other intelligence agencies to have access to data belonging to Americans in a way that represents an affront to the U.S. Constitution.
