FWIW, I don’t think this started with Obama. I think it stated long before Barry.
A quick read tells me that if they were going to sic dogs on Papadopolis while he was out of the country, they would have needed a warrant.
I think the problem with the Dems was NOT getting warrants on people they were "setting up". That eliminates the paper trail. Just pondering a bit.
“...started long before Barry.”
It all needs to be rooted out. Citizens have a right to know. I can see how difficult it is to access that knowledge as a matter of right shows you how those running the federal government (all 3 branches) don’t believe they ar ebeholden to the citizens.
Though to this point in time, there is nothing to suggest that W administration was spying on the demokraps, political enemies, etc and using a willing media and courts to plant lies about his opposition. Heck, W had harsher words for certain GOP, including Trump, than he had for any demokrap.
