To add to my last post. The Steele dossier was used to issue the FISA warrant. The Steele dossier has been proven to be a fabrication created to deceive. Submitting this false document is a felony.
Falsifying Documents | LegalMatch
An exceprt: Depending on the nature of the offense, as well as individual state laws, falsifying documents can result in a prison sentence of 5-10 years. Also, if government documents or federal authorities were involved, the legal penalties may be more severe. A maximum sentence for falsifying federal investigation and bankruptcy records can be fines and 20 year imprisonment.
Which means that since the evidence used to issue the FISA was a falsified document (a felony offense), the warrant was illegally issued and Trumps civil rights was violated.
