SCOTT SIMON, HOST:
This is WEEKEND EDITION from NPR News. I'm Scott Simon. What may be the most ambitious piece of legislation in the 113th congress, overhaul of the nation's immigration laws is now in the Senate Judiciary Committee. Committee members have proposed scores of amendments to the bipartisan legislation that had been hammered out by the bipartisan group called the Senate Gang of Eight.
Now all of these proposed amendments are making the prospects for ultimate passage of comprehensive immigration increasingly uncertain. NPR's David Welna reports.
DAVID WELNA, BYLINE: Here's Judiciary Committee Chairman Patrick Leahy's take on the long slog through the more than 300 amendments his panel's been considering for the immigration bill.
SEN. PATRICK LEAHY: This is going very well. It's moving a lot faster than people said it would.
WELNA: And Arizona's Jeff Flake, who's one of two Gang of Eight Republicans on the committee, thinks with the adoption of 15 GOP amendments so far, the bill's become more appealing to conservatives.
SEN. JEFF FLAKE: It's a better bill for, I think, those of us that care about border security and interior enforcement. It's a stronger bill.
WELNA: That's not how fellow Republican and committee member Jeff Sessions, of Alabama, sees it.
SEN. JEFF SESSIONS: None of the significant amendments have been accepted. It's pretty clear that the Gang of Eight's original statement that they would resist any significant changes to the bill, is coming true.
WELNA: Earlier this week, Sessions brought up an amendment putting the bill's promised path to citizenship for 11 million unauthorized immigrants on hold until biometric data, such as fingerprints or irises, are used to screen the entry and exit of every international traveler. South Carolina Republican and Gang of Eight member Lindsey Graham helped defeat it.
SEN. LINDSEY GRAHAM: I want biometrics as far as the eye can see, in as many ways as possible post-9/11, to protect this nation. But to make it a trigger, in light of how much it costs and how long it takes, I just think goes too far.
WELNA: But the issue has exposed a crack in the Gang of Eight's unity. One of its members who's not on the committee, Florida Republican Marco Rubio, says he's for a biometric entry-exit system.
SEN. MARCO RUBIO: The fundamental question is, can it be done in a cost-effective manner? And I think that's what we're going to - hopefully - explore here, in the next few days, leading into the floor debate. I hope that we can. I think it makes the system more effective.
WELNA: And even though California Democrat Dianne Feinstein voted against the biometric amendment, she'd like to see it considered when the bill goes before the full Senate, probably next month.
SEN. DIANNE FEINSTEIN: I don't think it's a deal-breaker, but I think we need to do our work. And I'm one Democrat that would like to see it eventually used if, if it is cost-effective - cost-efficient, I should say.
WELNA: Meanwhile, opponents of that path to citizenship are warning it could doom the entire bill. Ted Cruz is a Texas Republican.
SEN. TED CRUZ: The way to avoid the bill being voted down in the House of Representatives is to reach a reasonable, common-sense compromise; in particular, to take off the table that path to citizenship. So I hope that's what they choose to do.
WELNA: That would be the wrong choice, says Florida Republican Rubio.
RUBIO: If we can ensure the American people, and we can put in measures that ensure that we're not going to have another wave of illegal immigration, people are willing to support a bill that deals with the 11 million that are here now. And if we don't, I don't think we'll have immigration reform.
WELNA: Utah Republican Orrin Hatch could end up voting next week to send the immigration bill to the full Senate. That could persuade other key Republicans to get behind it, too. But Hatch first wants the committee to vote on changes he's offered, boosting the number of visas for highly skilled workers.
SEN. ORRIN HATCH: If they want to pass this bill through both houses, they've got to give on those, and I've got to have them.
WELNA: But Hatch will have to get past the opposition of Gang of Eight member and Illinois Democrat Dick Durban.
SEN. DICK DURBIN: Some of his amendments are acceptable, with some changes; and some are unacceptable. And, you know, when a senator basically says it's take it or leave it, he puts himself in a very weak bargaining position.
WELNA: Adding to the bill's uncertainty is an amendment Chairman Leahy has yet to bring up - allowing gay Americans to sponsor foreign spouses for green cards. Republicans in the Gang of Eight warn such a measure, if adopted, would be a deal-breaker. David Welna, NPR News, the Capitol.
