Republican Iowa U.S. Senate candidate Joni Ernst attempted Tuesday night to walk back statements made at a January event in which she said President Barack Obama had “become a dictator” who should be “removed from office” or face “impeachment.” In a statement provided to Yahoo News, reacting to a story published earlier Tuesday, Ernst said that she did not believe Obama is a dictator but rather “his repeated use of unilateral action sure makes him look like one.” “To be clear, I have not seen any evidence that the President should be impeached,” the statement read.
