The FISC warrant should never have been allowed. The judge that signed off on the warrant should have denied it, if he truly had knowledge that there was political motivation. If it is indeed true that the judge signed the warrant with full knowledge of the political motivation, he should be the one under criminal indictment.
The FBI has the "Woods protocol" that supposedly prohibits presenting FISC with unverified statements. The FBI should have never filed the warrant application. FBI set up FISC as a patsy. FBI is expert at setting up patsies, it's what they do best.
