“””I am really beginning to wonder if congressional investigators were provided altered fisa warrant applications by DOJ/FBI.”””
You are correct to be skeptical. I believe either Nunes or Grassley has issued a request to FISA Court to get the exact documents given to FISA Court by DOJ/FBI precisely because Nunes or Grassley does not trust the DOJ/FBI.
I have read that Nunes and/or Goodlatte are pushing for this.
Even Carter Page has requested all of the documents to be made public. He is still a question mark in my mind.
But there is no good answer here.
If the documents provided to congressional investigators were accurate, then it is almost a foregone conclusion that the FISA judges acted improperly. See Andrew McCarthys most recent article for more.
If the documents provided to congressional investigators were altered, that would create almost unimaginable problems for both DOJ and FBI, and the lawful administration of justice in this country.
