During an appearance on CNN's "State of the Union" this morning, President Trump's chief economic adviser Larry Kudlow said that Trump's unprecedented decision not to sign onto the G7 summit's joint communique came as a show of strength before his summit with North Korean leader Kim Jong-un: "POTUS is not going to let a Canadian prime minister...push him around on the eve of this. He is not going to permit any show of weakness on the trip to negotiate with North Korea."

The juice: Kudlow also said that Canadian Prime Minister Justin Trudeau "stabbed [the United States] in the back" with his denunciation of the U.S. decision to impose steel and aluminum tariffs after yesterday's conclusion of the G7 summit during an appearance. He added that Trump's choice not to sign the joint communique was "completely a reaction" to what he called Trudeau's "sophomoric play."
