Sen. Marco Rubio (R-Fla.) has split with his one-time political mentor, former Florida Gov. Jeb Bush, over a key aspect of immigration reform.

Rubio told reporters Monday evening that he disagrees with Bush’s position that illegal immigrants should not get a pathway to citizenship.

“I just personally, ultimately concluded that to permanently say that you’re going to have millions of people that can never apply for citizenship hasn’t really worked well for other countries that have tried it,” Rubio said. …

Bush said Monday that he does not support providing a pathway to citizenship for illegal immigrants because it would undermine the rule of law.
