Washington (CNN) - Three Republican Senators who are considered possible contenders for the 2016 GOP presidential nomination are all thumbs down on a bipartisan budget compromise that would prevent another government shutdown if approved by Congress.
Marco Rubio of Florida, Rand Paul of Kentucky, and Ted Cruz of Texas are critical of the deal struck Tuesday between House Budget Committee Chairman Paul Ryan, last year's GOP vice presidential nominee, and his Senate counterpart, Democrat Patty Murray, that would set spending levels, reduce the deficit, and relieve some of the forced spending cuts known as sequestration.
"I can't support the proposed budget deal," Rubio told supporters in an e-mail Wednesday, adding "this budget continues Washington's irresponsible budgeting decisions by spending more money than the government takes in and placing additional financial burdens on everyday Americans."
Paul said in a statement that "the small sequester spending cuts were not nearly enough to address our deficit problem. Undoing tens of billions of this modest spending restraint is shameful and must be opposed. I cannot support a budget that raises taxes and never balances, nor can I support a deal that does nothing to reduce our nation's $17.3 trillion debt."
Cruz, who was traveling back from the Nelson Mandela memorial service in South Africa while the deal was struck, did not directly react to the agreement.
But Cruz spokeswoman Catherine Frazier said in a statement that "while we haven't yet reviewed in full detail, the current budget proposal is deeply concerning. We shouldn't sacrifice the modest 2.4% spending cuts already in law in exchange for a mere possibility of future reductions."
A number of leading fiscal and grassroots conservative groups oppose the deal. Opposition could help any potential 2016 GOP White House contender with the kinds of voters who dominate the Republican presidential primaries and caucuses.
Ryan is also considered a possible contender for the next nomination. Asked Wednesday by CNN Chief Washington Correspondent Jake Tapper if he's concerned that his deal will hurt him in any future White House bid, Ryan pushed back.
"I was elected to solve problems here. I'm the chairman of the Budget committee," Ryan said.
"I'm going to do what i think is right, what the people in Wisconsin asked me to do, and I'm not going to let my personal political consideration down the road cloud that judgment. I don't think that's right. With the future, I'll let the chips fall where they may and I'll sleep very well," added Ryan.
