Section 702 is contentious, largely because it's so wide-reaching and doesn't require government agencies to get a warrant before conducting surveillance or searching through already collected communications. Groups like the Electronic Frontier Foundation and the ACLU have spoken out about the law and many have called for more oversight as well as protections for US citizens whose communications might fall under the law's scope. Last year, groups of senators, both Republican and Democrat, attempted to introduce reforms to Section 702 and Senator Rand Paul said at the time, "The American people deserve better from their own government than to have their internet activity swept up in warrantless, unlimited searches that ignore the Fourth Amendment."

The bill renewing Section 702 will now head to the president who is expected to sign it into law by the end of the week.
