MSNBC's Nicolle Wallace on Monday listed a series of damning and embarrassing reviews of President Donald Trump's performance at the G7 summit over the weekend, behavior which many observers have argued appears increasingly erratic and concerning.

"America's mad King George woke up to devastating reviews this morning of his latest turn on the world stage," Wallace said at the top of her show "Deadline: White House." One of the most crucial matters in which Trump's lack of clarity could have the most serious impacts is his trade war with China, which, Wallace said, may be "plunging the world into a global economic crisis."

She noted that the New York Times' Peter Baker said Trump's changing of positions at the G7 summit causee "geopolitical whiplash." Paul Krugman said he is "extremely unstable, in word and deed." Joe Biden said Trump's "disastrous foreign policy has left the United States isolated." Meanwhile, White House Press Secretary Stephanie Grisham is stuck cleaning up Trump's bizarre and false claim that First Lady Melania Trump has gotten to know North Korean dictator Kim Jong-un. (She hasn't.)
