U.S. Democratic presidential candidate Hillary Clinton responded to Republican presidential candidate Ben Carson's comments about Muslims on social media Monday. "Can a Muslim be President of the United States of America?" Clinton tweeted, with a picture of the Constitution. "In a word: Yes." Carson, a retired neurosurgeon, said Sunday, "I would not advocate that we put a Muslim in charge of this nation," which is a comment he has stood by despite the criticism he's received. Here's Clinton's tweet: Can a Muslim be President of the United States of America? In a word: Yes.
