Mark Penn, who owns a PR firm handling communications for the Barack Obama Foundation, credited Obama with uttering the “stupidest thing ever said by a president in foreign policy.”

According to Washington Free Beacon, in a March 2012 email sent to Hillary Clinton’s private email address, Penn thrashed Obama for his statement to then-Russian President Dmitri Medvedev that he would “have more flexibility” on missile defense issues after the 2012 election.

“This could be about the stupidest thing ever said by a president in foreign policy,” wrote Penn. “To explicitly say that he is laying low on nuclear defense policies because of his election right now and tell your opponent that is to politicize all foreign policy, evidence weakness that can be exploited by others, and undermine the administration’s credibility.”

SKDKnickerbocker, the Penn owned firm was paid $230,436 for marketing and communications work by the Barack Obama Foundation. Obama plans to use the foundation as the main vessel for his post-presidency political work. The firm brings unparalleled strategic communications experience to Fortune 500 companies, non-profits, philanthropic organizations, labor unions, and political committees and candidates, calims it’s website.

Penn recommended that Clinton should “consider resigning” if the administration’s foreign policy positions were truly being swayed by Obama’s campaign for reelection. He also cautioned that enemies “from al Qaeda on down” will use Obama’s words to their advantage.

Penn’s opinion that Obama said the “stupidest thing ever said by a president” is just the latest indication of how negatively Penn views Obama. As a top campaign strategist for Clinton in 2008 Penn recommended a negative campaign strategy that focused on Obama’s “lack of American roots.”

Earlier this year, Billionaire Republican presidential candidate Donald Trump took a jab at President Obama, saying that the American people were being “led by very, very stupid people.”

Donald didn’t stop there with his berating of Obama, saying that “with incompetent leadership we have right now, Israel will not survive,” this as the “Supreme Leader” of Iran, as Obama refers to him as, stated that “Israel would not exist in 25 years.”
