Nice try but Yahoo Fake news is trying use point 1 below to negate point 2 below.
1) FBI planted a human being to spy, which they now say was to protect Trump.
2) Obama's FBI spied on the Trump Campaign with electronic surveillance.
As you are a Fake news Victim, you have been duped yet again. 
Idiot, its called a confidential informant. It is standard practice within the FBI. Crawl out from under your rock, that is how the FBI collects evidence. Nothing illegal about it. Trump uses the word spy to fire up all the dumbasses like you that make up his base. You know the 36% of the morons that still support him.
