John Brennan, who served as CIA director in the Obama administration, took a shot across the bow at President Trump after the president lashed out at Canadian Prime Minister Justin Trudeau for being “dishonest” and “weak."

In a pointed tweet Sunday morning, Brennan said Trump is "a temporary aberration" whose impact on the U.S. will not last.

"Your wrong-headed protectionist policies & antics are damaging our global standing as well as our national interests. Your worldview does not represent American ideals. To allies & friends: Be patient, Mr. Trump is a temporary aberration. The America you once knew will return," Brennan said.

Hours earlier, Trump accused the Canadian leader of acting “meek and mild” during their meetings in Quebec during the G-7 summit and being “dishonest” in the way he portrayed the newly imposed U.S. tariffs. He also claimed to have informed U.S. officials not to affirm the communique signed by G-7 members.

Following Trump's Saturday departure from the G-7 for Singapore, Trudeau held a press conference stating that all of the member nations, including the U.S., had signed a communique dedicated to lowering tariffs and other trade barriers. He also said in response to Trump's tweets that "We are focused on everything we accomplished here at the summit. The Prime Minister said nothing he hasn’t said before — both in public, and in private conversations with the President."

The tweet from Brennan, a vocal critic of the president, echoed that of one sent by James Comey, the ex-FBI director who was fired by Trump last year.

"Our national security relationship with Canada is vital and saves American lives. It was built over generations and is bigger than any person or dispute. This too shall pass," Comey tweeted early Sunday.
