Conservative party member and Canadian Environment Minister Peter Kent. Like most members of the Canadian conservative party, Peter Kent is shamelessly partisan in all he does and says. He slavishly follows party talking points and directives, and is willing to destroy his country's reputation and democratic principles in order to increase the power of his party.
So really, while Peter Kent certainly is a piece of shit, he isn't really any bigger of a piece of shit than Stephen Harper or anybody else in the conservative cabinet.
Peter Kent: "I'm going to ban attendance at a major environmental conference for anyone who's not a member of the conservative party, and then I'm going to openly mock my parliamentary opponents for the fact they didn't attend the conference."
Justin Trudeau: "You piece of shit."
