US President Biden on April 20 signed a legislation renewing a crucial US surveillance law amid debate over its misuse. The Senate voted 60-34 to extend the Section 702 program of the FISA for two years on April 19.

The surveillance tool was first authorised in 2008 and has been renewed several times since then. Watch the video to know more.
