So, your candidate and/or someone in his campaign was picked up by spying on Russian agents, and it is the Democrat's fault.
If a judge OK a warrant, doesn't that make it legal.?
Please provide the evidence / links to support you BS....
And the answer to your question is NO. If an unsubstantiated document obtained from a foreign spy through a company working for the Russians is used as a basis to obtain a warrant to spy on an opposing political candidate during an election it is NOT legal.
Rosenstein and Mueller (proven with links posted last week, and before) prove Rosenstein have a documented history of breaking laws, hiding evidence, lying, and trampling witnesses' right to get what they want. They have billed witnesses, withheld evidence that would have prevented innocent people from going to jail, and concocted fake crimes to send innocent people to jail.
This would be just another crime they have committed. Rather than just be fired, again, Rosenstein should be PERP-WALKED if this turns out to be true.
