Sen. Marco Rubio (Fla.), the only Senate Republican of Hispanic heritage and a possible vice presidential pick, is working on an alternative version of the Development, Relief and Education for Alien Minors (DREAM) Act, which would grant legal status to illegal immigrants who came to the country at a young age and serve in the military or attend college.

He declined to provide any details, but confirmed he hopes to have legislation soon.

“I don’t have any specifics to announce yet,” said Rubio. “This stuff has to be done responsibly. We’re working toward that and hopefully very soon.”

Sens. Jon Kyl (R-Ariz.) and Kay Bailey Hutchison (R-Texas) are also working on a bill, although its details are being kept secret, according to congressional sources. Senate sources expect it to be unveiled after GOP front-runner Mitt Romney has clinched the presidential nomination.

A spokeswoman for Hutchison declined to comment, while a spokesman for Kyl did not respond to several requests for comment.
