TRENTON, N.J. (AP) – New Jersey Gov. Chris Christie says President Barack Obama has failed to lead on debt reduction talks.

The United States will default on its debt in two weeks unless a deal is reached to raise the debt limit, so lawmakers in Washington are scrambling for a debt reduction plan to break the gridlock.

Christie says it’s up to Obama to lay out a plan, saying the president has an obligation to lead. And if Obama doesn’t do that, Christie says government “gets in paralysis.”

The first-term Republican governor is often mentioned as a potential challenger to Obama next year despite repeated insistences that he’s not going to run.

Christie declined to comment on a specific deficit reduction plan because the deal keeps changing.
