The Republican candidate for Senate in Minnesota has come under scrutiny for a Facebook post in which she said a chimpanzee had better posture than former first lady Michelle Obama.

Karin Housley, a Minnesota state senator, made the comment in 2009 after Obama met Queen Elizabeth II in London's Buckingham Palace, according to the Huffington Post on Monday.

“Michelle is soooo far from cool. Don’t we expect our First Ladies to at least stand up straight? (And my dear sister, know the proper etiquette and DO NOT TOUCH THE QUEEN!),” Housley wrote on her Facebook Wall.

“I do miss Nancy Reagan. Ronald even more. Speaking of Bedtime for Bonzo, I think even that chimp stood up straighter than Michelle,” Housley wrote in a follow-up remark. “Uh-oh, someone is going to make a comment.”

"Bedtime for Bonzo" was a 1951 film starring former President Ronald Reagan, in which he plays a professor who tries to apply human child-raising techniques to a chimp.

Housley's campaign condemned the Huffington Post as "an extension of the Democratic Party" for reporting on her statements, which may be interpreted as being racially charged.

"This is what the radical left does when they are losing — they attack Republicans so they don’t have to come up with solutions to the problems Minnesotans are facing,” Housley spokesman Jake Schneider told the outlet.

Schneider did not immediately respond to the Washington Examiner's inquiries.

Housley appears to be trailing Democratic Sen. Tina Smith in the state's 2018 special election for a permanent replacement for former Sen. Al Franken, according to RealClearPolitics' poll aggregator. Franken stepped down in December after being accused of sexual misconduct.
