Trump may not be against FISA for the reasons I am but I am glad he intended on vetoing it.

was just another "good idea" until it was abused, and used as a political weapon.

https://en.wikipedia.org/wiki/Foreign_Intelligence_Surveillance_Act

The Foreign Intelligence Surveillance Act (FISA) was introduced on May 18, 1977, by Senator Ted Kennedy and was signed into law by President Carter on 25 October 1978. The bill was cosponsored by nine Senators: Birch Bayh, James O. Eastland, Jake Garn, Walter Huddleston, Daniel Inouye, Charles Mathias, John L. McClellan, Gaylord Nelson, and Strom Thurmond.

The FISA resulted from extensive investigations by Senate Committees into the legality of domestic intelligence activities. These investigations were led separately by Sam Ervin and Frank Church in 1978 as a response to President Richard Nixon’s usage of federal resources, including law enforcement agencies, to spy on political and activist groups.^[2][3] The law itself was crafted in large part in closed door meetings between legislators and members of the Justice Department.^[4] The act was created to provide judicial and congressional oversight of the government's covert surveillance activities of foreign entities and individuals in the United States, while maintaining the secrecy needed to protect national security.
