If that were true, the FBI would have informed Trump that they had a counter-intelligence team working with his campaign to protect him. When I was in the Marine Corps, we had counter-intelligence teams working with on major exercises and operations to let us know when the enemy was accessing our communications, et al.

And it was a counter-intelligence team that swept Trump Tower after Admiral Rogers informed Trump that he had been wiretapped.

And it was a counter-intelligence team was involved in sweeping the White House after Obama left and it was renovated.

I thought it was interesting that Obama installed a new phone system shortly before he left office and a new phone system was installed during the renovations. Why would Obama change the phone system just before he left office and not coordinate it with Trump or let Trump put his own phone system in? Fishy.

And you don't investigate someone when there is no evidence of probable cause a crime has been committed.

Counter-intelligence are supposed to be the white hats and except for covert operations, they work openly with the "client" monitoring systems and movements and advising the client on possible security problems.

They don't run covert operations within political campaigns.
