For the second day in a row, Senate Republicans sparred publicly about the budget, with Sen. Ted Cruz (R-Tex.) saying bluntly that he does not trust his party to resist a compromise on the debt ceiling.

As Lori Montgomery explained, moderate Senate Republicans want to name a conference committee to reconcile differences between the Democrat-led Senate budget and the GOP-controlled House budget. Conservative Republicans are resisting, saying that the conference might result in a debt ceiling increase -- even though the House would have to sign off on the deal.

On Tuesday, McCain described that position as "bizarre." He added Wednesday, "Basically here what we're saying on this side of the aisle is we don't trust our colleagues on the other side of the Capitol who are in the majority..."

Cruz replied that McCain was correct, saying both parties are to blame for the national debt.

"Let me be clear: I don't trust the Republicans. And I don't trust the Democrats," he said. "And I think a whole lot of Americans likewise don't trust the Republicans and the Democrats, because it is leadership in both parties that has gotten us in this mess."

The freshman senator has previously described moderate Republicans as "squishes" who were afraid to take a stand on gun rights.
