NYC Mayor Bill de Blasio: Trump's shooter comment shows he's 'not presidential'

The mayor of New York City says Donald Trump's prediction that he could shoot someone and not lose support in the polls is "incredibly sensitive," and shows he's not ready to be president.

"We had a moment in our nation's history we're talking about how to deal with the scourge of gun violence," Mayor Bill de Blasio said on ABC's "This Week" on Sunday. "And for someone who says he wants to be president to say that, it shows he's just not presidential."

"And it's incredibly arrogant, too, for him to suggest that his voters will be with him no matter what he does," de Blasio added. "You know, this is another indicator that Donald Trump is not ready for primetime."

At a rally in Iowa on Saturday, Trump told a crowd, "I could stand in the middle of Fifth Avenue and shoot somebody and I wouldn't lose any voters, OK?" The comment was a reference to the loyalty of his supporter base and the several months of polls that show the businessman at or near the top of the Republican field.
