Did Obama Bug Trump Tower?

(UPDATED)
According to several sources, including a piece in the Guardian from January 11, the Obama DOJ (FBI) did attempt to obtain FISA warrants to bug Trump associates.  Here's the paragraph:

The Guardian has learned that the FBI applied for a warrant from the foreign intelligence surveillance (Fisa) court over the summer in order to monitor four members of the Trump team suspected of irregular contacts with Russian officials. The Fisa court turned down the application asking FBI counter-intelligence investigators to narrow its focus. According to one report, the FBI was finally granted a warrant in October, but that has not been confirmed, and it is not clear whether any warrant led to a full investigation.

Once again Trump is most likely right.

Was this justified or just a ruse to gain compromising information? If the FBI has proof Trump is a Russian agent and is doing Putin's bidding, why keep it secret?   Why allow Trump to set-up a rogue government just to have it all scrapped as he's hauled off to prison for treason?  

And once again James Comey has a lot to explain. 

UPDATE: In addition to the above, the New York Times, no ally of Trump's, reported on January 20th about "wiretaps" which grabbed information on Trump associates.  (UPDATE 3/9: The Times has changed their headline online to better fit their current narrative.  Haha. Hat tip to Andrew McCarthy who has been unequaled in his commentary on all this.) 

But all the evidence of eavesdropping notwithstanding, it is probably besides the point. Trumps tweet about Barack Obama wiretapping him is brilliant on several levels:  

• Right before Trump's tweet, Reince Priebus had approached James Comey and asked him to state publicly what he was already saying privately, that there was no collusion between Trump and Russia.  Comey turned him down flatly saying the FBI doesn't get involved in political arguments.  Then Trump tweets, and Comey IMMEDIATELY denies any wiretapping by Obama!  Trump smoked him out, uncovered his hypocrisy, and now knows which side his FBI director is on. 
• Leaks of wiretapped phone calls and private conversations have been dogging Trump since day one.  Now that he has implicated Barack Obama, the price for leaking has gone up exponentially for the left.  Any new leaks further implicate Barack Obama who doesn't want anyone, much less a special prosecutor, digging into his business.  
• Note that Obama's response to Trump's tweet did not deny any wiretapping!  He just denied ordering it, and laid the blame on Loretta Lynch and the DOJ.  (Side note: Loretta Lynch has been calling for violent insurrection against Trump lately.  See here.)
• Democrats have been spun-up calling for congressional investigations, independent prosecutors, and media investigators to look into the dubious claims of Russia collusion in the Trump campaign.  Now the playing field is level and both claims must be taken equally seriously.  Guess which side has more exposure now?
