The No. 2 Republican in the Senate says he would quit the special deficit-reduction supercommittee if there is an effort to cut more from defense.
Arizona Sen. Jon Kyl made the remarks Thursday at a defense forum shortly after the first supercommittee meeting. Kyl said he is "off of the committee if we are going to talk about further defense cuts."
The debt-limit bill that Congress approved last month calls for $350 billion in military reductions over 10 years.
At the supercommittee meeting, Kyl had commented on a "sense of optimism" that the panel could succeed in cutting $1.5 trillion from the deficit.
The forum was sponsored by the American Enterprise Institute and the Heritage Foundation.
