Lawmakers have been pushing to pass legislation that would give FBI agents the right to read email logs, an IP address and Internet browsing history without a warrant. The legislation, led by senators John McCain (R-Ariz.) and Richard Burr (R-N.C.), came in response to the Orlando shooting, and was just two votes short of what it needed to succeed. The bill, which is expected to return to Congress, would only require FBI investigators to get permission from their field supervisor in order to access personal Internet data.
