Just their handling of the border (or lack thereof) proves they can’t be trusted with FISA and FISC.
If you followed Hillary’s Russia, Russia, Russia concoction and its entry into the FISA/FISC process with collusion by the DNC, FBI and DOJ you’d see just how evil FISA/FISC is. Remember the Trump hating FBI agent and his girlfriend? Peter Strzok (Agent) and Lisa Page (FBI Lawyer). They worked within the FISA process against Trump
After the initial warrant request submission, they all were supposed to come back to the FISC in 90 days with MORE and different information to back up the initial request. What they submitted were rehashed MSM stories of the original fraudulent Steele BS material created for Hillary’s use against Trump.
Intentional misuse and abuse happens like this every day with FISA and the FISC rubber stamps virtually ALL of it with something like a 99% approval rate.
