WASHINGTON -- President Obama's chief of staff said Sunday morning that the administration had privately drafted an immigration bill so that it can "be ready" if lawmakers ultimately fail to agree on their own version of an overhaul of existing laws.
But the chief of staff, Denis McDonough, the president's top White House official, said Mr. Obama's aides are continuing to work with a bipartisan group of eight senators despite harsh criticism on Saturday night from a key Republican after a newspaper reported what it said were details of the administration's plan.
"We've not proposed anything to Capitol Hill yet," Mr. McDonough said on the ABC News program "This Week" in his first appearance as chief of staff. "We're just going to be ready. We have developed each of these proposals so we have them in a position so that we can succeed."
USA Today reported on Saturday that early drafts of the White House legislation called for immigrants to wait eight years before becoming permanent residents. The report drew a scathing response from Senator Marco Rubio, Republican of Florida, who said the plan would be "dead on arrival" in Congress.
"It's a mistake for the White House to draft immigration legislation without seeking input from Republican members of Congress," Mr. Rubio said in a statement late Saturday night.
The White House has declined to confirm the paper's report, and Mr. McDonough did not say what specific proposals were in the president's legislation. But he said they would be revealed if lawmakers could not reach an agreement.
"He says it's dead on arrival if proposed?" Mr. McDonough said of Mr. Rubio's comments.
"Well, let's make sure that it doesn't have to be proposed; let's make sure that that group up there, the gang of eight, makes some good progress on these efforts, as much as they say they want to," he said referring to the bipartisan group of senators. "That's exactly what we intend to do, to work with them."
The USA Today report said that the president's draft legislation would allow illegal immigrants to apply for a "Lawful Prospective Immigrant" visa before they became eligible for permanent resident status.
Those details are similar to the statement of principles that the White House provided to reporters after a speech Mr. Obama gave in Las Vegas last month concerning immigration. A fact sheet said the president wanted to strengthen border security, provide "earned citizenship," streamline legal immigration and crack down on employers who knowingly hire illegal immigrants.
"Immigrants living here illegally must be held responsible for their actions by passing national security and criminal background checks, paying taxes and a penalty, going to the back of the line, and learning English before they can earn their citizenship," the fact sheet said. "There will be no uncertainty about their ability to become U.S. citizens if they meet these eligibility criteria."
In his statement, Mr. Rubio criticized Mr. Obama, saying that the details reported in the USA Today article represented legislation that "is half-baked and seriously flawed."
"It would actually make our immigration problems worse," he said. Mr. Rubio has been among the leading Republicans pushing for a comprehensive overhaul of immigration.
Senator Charles E. Schumer, Democrat of New York, said Sunday that despite the criticism he remained optimistic about the chances of reaching a bipartisan agreement in March.
"We've talked to Senator Rubio, and he's fully on board with our process," Mr. Schumer said on CNN's "State of the Union," adding that the president assured lawmakers last week that they should take the lead. "He agreed to give us the space we need to come up with a bipartisan proposal."
Demetrios G. Papademetriou, president of the Migration Policy Institute, an independent nonpartisan research center in Washington, said the eight-year temporary status for illegal immigrants in the document obtained by USA Today was "essentially the same as the probationary status" envisioned in a proposal developed by the bipartisan group. During the probationary period, Mr. Papademetriou said, immigrants would have temporary visas with full work authorization.
The bipartisan Senate proposal calls for additional border security and more effective enforcement to curb illegal immigration. And it would require that "enforcement measures be completed before any immigrant on probationary status could earn a green card." It was not immediately clear whether the White House would support such linkage.
Mr. Obama's administration has been working on immigration legislation for years. But the issue shot to the top of the president's second-term agenda after his re-election in November, when Hispanic voters backed him in large numbers. White House officials are betting that Republicans will be eager to embrace immigration changes as a way of repairing their image with an important voting bloc.
But passage remains tricky, especially in the Republican-controlled House, and Mr. Obama has made it clear that he will take a back seat to lawmakers if it will help. Negotiations are taking place among the senators, a separate group in the House, labor leaders, and the U.S. Chamber of Commerce.
Representative Paul D. Ryan, Republican of Wisconsin, praised Mr. Obama's tone on the issue last week, saying the president "actually doesn't want to politicize this, which is conducive to getting something done."
On Wednesday, the White House said Mr. Obama met with Democratic senators at the White House to get a status report on the pace of progress on the legislation. In a statement after the meeting, White House officials said the president reiterated his pledge to become more involved if necessary.
The statement said Mr. Obama told them that he expected "the process to continue to move forward and stands ready to introduce his own legislation if Congress fails to act."
It remains unclear how long the president is willing to wait. In interviews with Spanish-language television stations after his speech last month, Mr. Obama suggested that he wanted to see real progress by March.
"If they can get a piece of legislation debated on the floor by March I think that's a good timeline. And I think that can be accomplished," he said on Univision last month. "I'm not going to lay down a particular date, because I want to give them a little bit of room to debate. If it slips a week, that's one thing. If it starts slipping three months, that's a problem."
