Manhattan U.S. Attorney Preet Bharara is not doing much to encourage speculation that he's one of the few people being considered to be the next attorney general. And he's not exactly discouraging it either.

Bharara has overseen dozens of insider trading cases and some important terrorism trials during his five years in New York City. He's considered to be among fewer than 10 top candidates for the job being vacated by Attorney General Eric Holder.

At a public appearance on Tuesday, he made light of the speculation, saying that his loving mother was trying to drum up interest on his behalf. But he also signaled that things wouldn't change too much if he was in charge. He says national security, cyber-crime and civil rights would remain top priorities.
