Lou Dobbs, who recently resigned from hosting a nightly show on CNN, said in his first interview since his resignation that he is "going to remain in the public arena."

Dobbs was asked by Fox News' Bill O'Reilly if he is considering a Senate run in New Jersey.

"A lot of things are on my mind, I'm not going to be coy about this," Dobbs said, though he neglected to answer the question directly. He went on to say he is "thinking about a lot of opportunities."
