Flake's floor speech comes as Trump and GOP administration staffers have clashed publicly with Canada following the Group of Seven (G-7) summit. Trump left the meeting to meet with North Korean leader Kim Jong Un.

Flake added that concerns with allies shouldn't be addressed through "bellicose taunts or tweets."

"Consistently ridiculing our allies by suggesting that they are somehow abusing us while voicing admiration for despots and dictators represents a fundamental departure in behavior for American administrations," he added.
