"I want to wait and see what the details are," Cruz said. He's expected to get them at a Tuesday Senate Republican caucus meeting, scheduled for 11 a.m. ET.
His ultimate answer is important, with the federal government scheduled to default on its obligations starting as soon as Thursday. Senate Majority Leader Harry Reid (D-NV) and Senate Minority Leader Mitch McConnell (R-KY) seem close to a deal that would fund the government until mid-January and raise the debt ceiling until early February.
With Thursday's deadline looming, the leaders are likely hoping for unanimous consent to advance it through the Senate as quickly as possible. An objection from Cruz or one of his allies could stymie that plan.
