It sure seems like a fishing expedition; the investigation should have ended with Comey. Comey should have been subpoenaed and Clinton should have been investigated. Instead special counsel is now investigating this President, though Comey finally stated that he wasn't under investigation to begin with! I'm not so sure that I agree with Cruz that Mueller is honorable. It seems to me that Trump should fire both Mueller and Rosenstein.
Ted Cruz says Russia investigation shouldn't become 'fishing expedition'Texas Sen. Ted Cruz said Friday that he hoped the investigation into Russia's involvement in the 2016 presidential election and that country's ties to President Donald Trump's campaign won't turn into a "fishing expedition."
"Bob Mueller is a good and honorable man, but I certainly hope that the appointment of a special counsel doesn't turn into a fishing expedition," Cruz said during a stop in Arlington. "There's a reason that special counsels and independent counsels have gone adrift in the past. It's because they allowed their mandate to encompass everything in a massive fishing expedition. That would be an abuse of the terms of the appointment, so I hope that's not happening."
