Republican strategist Steve Schmidt said Sunday that President TrumpDonald John TrumpHouse Republicans move to block Yemen war-powers votes for rest of Congress Trump says he's considering 10 to 12 contenders for chief of staff Michael Flynn asks judge to spare him from jail time MORE “beclowned himself” and disgraced the United States at the Group of Seven (G-7) summit.

“From his slovenly appearance to his unpreparedness, ignorance and arrogance, he beclowned himself,” tweeted Schmidt, one of the loudest GOP critics of Trump. “The Republican majority is filled with cowards who are servile supplicants to the most unfit POTUS ever.”

 

Schmidt, a former aide to Sen. John McCain (R-Ariz.) and an MSNBC analyst, also called Russian President Vladimir Putin “the greatest intelligence agent —ever” in a separate tweet.

“He has engineered the unraveling of the western alliance, fidelity to democracy in the United States and the severing of the [United Kingdom] from the [European Union]. It’s a remarkable achievement,” he tweeted of Putin.

 

Schmidt has been highly critical of Trump and his administration. Earlier this year, he compared Trump’s staff to monkeys "hurling their excrement at each other."

Trump made headlines on Friday when he called for Russia to be readmitted to the G-7, after being removed over the annexation of Crimea. Other world leaders in the group rejected the proposal.

Trump also refused to back a joint communique issued by the participating nations at the end of the summit, and slammed Canadian Prime Minister Justin Trudeau as “very dishonest & weak.”
