It's fair game to disagree with McCain on policy. I sure as hell often do. But your accusation he gave classified information to the enemy cannot stand.

"Because of the seriousness of the charge, the utter absence of evidence and the clear intention to harm McCain just days before a critical Republican primary, we find this claim to be Pants on Fire wrong."
I honor our veterans, especially ones like John McCain who endured so much in service of our country. He is a war hero for
not sharing sensitive information with the enemy. How many others would have had his strength and valor?
Meanwhile, guess who
did share classified information with our adversary?
Donald Trump 'shared highly classified information with Russian officials'

Pretty much the entire Republican majority is guilty of this too. Don't forget how they voted to release Devin Nunes' memo of classified intelligence he cherry-picked to fabricate a story line intended to discredit the Mueller investigation. The FBI and the Justice Department warned that doing so would severely undercut their intelligence gathering capabilities and put their sources at grave risk. Trump was involved too, of course. He declassified the material in order to pave the way for its release.
This is the behavior of an autocrat discarding the best interests of our country for his own self-preservation, and a party of sheep willing to do whatever he says.
