No.

First, FISA was created in 1978 to protect Americans from the CIA by forcing them to show probably casuse. Section 702 of FISA is about intercepting any foreigners communications for which they need no warrent.

But the CIA incidentally collects data of U.S citizens during these warrentless wire taps, and that would be the 4th amendment challenge, but so far that is going nowhere.

The constitution lost its power long ago, and is now a mere fig leaf of legitimacy. Plenty of things ought to be unconstitutional based on a plain reading of the constitution. Civil forfeiture, unlimited gun rights, qualified immunity, FISA courts, various “emergency” powers, deportation of US citizens, etc, etc. The trouble is that a huge portion of Americans don’t really care about any of this, so long as these violations are used to stick it to liberals, all is forgiven.
