On Monday, Republican presidential hopeful Donald Trump called for a "complete shutdown" of Muslims entering the U.S. for any reason. It didn't take long for his 2016 opponents to start denouncing that idea:
One of the first to do so was another Republican, New Jersey Gov. Chris Christie:
Democratic longshot Martin O'Malley was quick to label Trump as "fascist."
Sen. Lindsey Graham (R-S.C.) called Trump "downright dangerous."
Former Gov. Jeb Bush (R-Fla.) said the billionaire business mogul is "unhinged":
Here's another Republican presidential hopeful, Carly Fiorina, weighing in:
Sen. Ted Cruz (R-Texas) had a less forceful reaction, but still a negative one:
Hillary Clinton called Trump's statement "reprehensible."
Sen. Bernie Sanders (I-Vt.), Clinton's closest competition for the Democratic nomination, cautioned Americans against "allowing racism and xenophobia to divide us."
Gov. John Kasich (R-Ohio) joined in, calling Trump "entirely unsuited to lead the United States."
Sen. Marco Rubio (R-Fla.) shared that he found the "outlandish" remarks to be divisive.
Finally, former New York Gov. George Pataki (R) jumped into the fray and called Trump's comments "idiotic."
