No, he is asking for those to be released so that he would be cleared in "court of public opinion" from "treason/collusion" charges (because Mueller investigation can take years as everyone keeps telling here).
And that whoever leaked the fact about FISA warrant on him to press is guilty of felony.
How is that relevant to statement from Manafort spokesman?Are you not reading your links?
No article gives actual clear link between supposed indictment (that hasn't came about yet) and those FISA recordings - all connection so far is only "happened to same person", no leaks showing that this info actually led to anything.
