One would hope that the warrant was issued because of serious actual evidence of wrong doing. They have to know it is going to face a huge amount of scrutiny so it better stand on its own. But this is also DC and politics reign supreme...
Agreed. On what basis was the warrant issued and why?? What did the warrant have to actually do with Russian collusion? Why was Mueller going beyond the scope of what he was authorized to investigate? If there was no evidence of collusion than anything after that is simply a witch hunt and he's looking under any rock possible and hoping to find something.
Perhaps not unconstitutional but seemingly unlawful and certainly unethical. He overstepped his authority period; except Rosenstein really never set down any defined parameters making it an on going investigation that won't end until they completely derail his presidency.
