A comprehensive immigration overhaul bill is not expected until mid-April at the earliest, but four members of the Senate Gang of Eight – the team of bipartisan senators tasked with creating an immigration bill- will visit the Arizona-Mexico border today.

The two Arizona senators – both Republicans and Gang of Eight members, Sens. John McCain and Jeff Flake – will host Democrats Chuck Schumer of  New York and Michael Bennet of Colorado for a tour along the border in Nogales, part of the Tucson sector. They will hold a news conference after the visit.

The visit comes in advance of the pending immigration legislation to bring 11 million undocumented on a possible path to citizenship.

At a Monday town hall meeting, McCain said the team has made progress in “a number of areas” that he is “encouraged” by, but there are still areas on which the team has been unable to come to agreements.

“I don’t know if we can achieve agreement or not,” he said. “We have been working, literally, night and day. We may not succeed.”
