(CNN) – Another Republican has voiced interest in challenging President Obama for the White House in 2012.
John Bolton, former U.S. ambassador to the United Nations, said Sunday he's "considering" a run.
"Yes, I am considering it," Bolton told conservative radio show host Aaron Klein's on WABC in New York. "If I did run, and I haven't made a decision, I have never run for office one way or the other, so it would be a pretty big decision to do it."
Bolton, who serves as a Fox News commentator, said he's concerned that the national discourse does not include talk of foreign policy.
"I'm very concerned about the direction of national security policy," Bolton said. "I'm concerned that we hardly talk about it at national-level debates in the mainstream media."
He also said the president seems to view national security issues as an "irritation, a distraction from what his real priorities are."
In the interview Bolton said Obama "doesn't enjoy being commander-in-chief," and that it's important the Republican Party nominate a strong candidate because the president "gives a pretty good speech."
"It's important to be able to take him on intellectually and at a policy level in a very direct way, and that's one of the things I'll be considering," Bolton said.
Bolton served as the under secretary of state for arms control and international security in the George W. Bush administration before he was appointed to the U.N. position and is currently a senior fellow at the conservative American Enterprise Institute for Public Policy in Washington.
