New York City Mayor Michael Bloomberg, an outspoken advocate of stricter gun-control laws, said in a radio interview Friday the two candidates for president needed to take a firmer line in addressing gun violence.

"Soothing words are nice, but maybe it's time that the two people who want to be president of the United States stand up and tell us what they are going to do about it, because this is obviously a problem across the country," Bloomberg said on WOR Radio's "The John Gambling Show."
