John McCain perfectly mocks Trump's cyber alliance with Russia: Putin can help 'since he's doing the hacking'

Sen. John McCain (R-AZ) threw cold water on President Donald Trump's plan to team up with Russian President Vladimir Putin to form a "cyber security unit" that he claims will prevent future election hacking.

Trump revealed the plan in a tweet on Sunday.

"I am sure that Vladimir Putin could be of enormous assistance in that effort since he's doing the hacking," McCain laughed sarcastically during an interview on CBS.
