"There's no question that we should be able to look at any past president, whether they're married to someone running for president or not, in terms of their behavior and what it means," Carson said during Thursday's GOP presidential debate in North Charleston, S.C.
Carson continued, questioning the country's standards: "Is this America anymore? Do we still have standards? Do we still have values?"
Carson called for unity among Americans, saying the "divisiveness and hatred" pervasive in the country does not stem from Judeo-Christian values.
"Where did that spirit come from in America? It did not come from our Judeo-Christian roots I can tell you that," he said to applause.
"Our strength is in our unity," Carson added. 
GOP presidential front-runner Donald Trump has repeatedly blasted Bill Clinton’s sex scandals and called him “one of the great woman abusers of all time.” 
Trump said Clinton was fair game after Hillary Clinton accused him of having a "penchant for sexism."
Trump has also called the former secretary of State "an enabler" of sexual assault.
