Brennan is starting look like a loose cannon. I can see how this would happen, since he's now out of the loop, and has no access to the tremendous amount of information he once had. Not only is he in the dark, his ability to misuse his security clearance for a lucrative future is now gone.
Considering the number of people either getting the ax, or resigning in the FBI, and the DOJ, those involved with the effort to derail Trump are now in the dark, and can't plan their actions by using the inside connections they once had. Communicating with such people, even if they have a security clearance, can lead to some nasty things for those still working for the government. Unless there's a really strong friendship, I doubt many will want to do any favors, and anyone caught revealing classified information may find punishment more severe than just being fired. This also affects the media connections, since the hostile media is now shunned by the current administration.
NBC lost a valuable inside source, when Brennan lost his security clearance, and I doubt they keep him much longer. His conjecture is useless, and his bitterness will only lead to a loss in ratings. Finding someone as valuable will be very hard, since it's now known Trump doesn't play softball, and those that caused so many problems are being removed.
It's what they don't know that leads to the outlandish media reports. Where they once had unfettered access to the government in the past, they are now finding doors closing, and their actions being closely monitored. Their attacks against the present administration had to have hurt ratings, and further efforts to cause problems will only lead to more losses. For the media, that's what leads to massive turnovers, loss of stock value, panicked efforts to find qualified management, and the realization their membership in the Washington "country club" may soon end.
It's a terrible thing, when many in the media are complicit in trying to overthrow the government, and helping foment anarchy. Some might be acting completely out of ignorance, but others obviously know the dangerous path they ventured. Regardless of the reason, those involved need to have their wings clipped, and responsible people need to remove their revenue by refusing to watch, link, or subscribe to the outlets participating in trying to change the U.S. by ignoring the avenues for change offered by the Constitution.
