I heard about this scandal (and it is a scandal) in an email, and went to find it by Googling, which gave me this:

Rubio hires powerful Democratic lawyer to help write immigration bill [1]
Daily Caller - 3 hours ago
The lawyer, Enrique Gonzalez, is a partner at the nation's largest immigration firm.
However, when I clicked, the headline had changed to
Rubio hires immigration lawyer who imports workers for companies [2], By Neil Munro, March 21, 2013
Presumably as a result of an update. Neil Munro, who's been doing good work on immigration, [3]writes:
Florida Republican Sen. Marco Rubio’s top lawyer in the closed-door effort to draft a new immigration bill is a Democratic donor who earns his living by bringing foreign workers into the country on behalf of corporations and universities.
The lawyer, Enrique Gonzalez, is a partner at the nation’s largest immigration firm whose future depends on the outcome of Gonzalez’s closed-door work.
Rubio hired Gonzalez in January, when he was a partner at the Coral Gables, Fla., office of Fragomen, Del Rey, Bernsen & Loewy.
We've got two pages of articles and posts referring to Fragomen [4], none of them in a good way. [5]
This raises two questions:
Question One: Which is Rubio is more deficient in: party loyalty, [6] or loyalty to the United States of America? [7]
Question Two: Which is Rubio more loyal to: his fellow "Hispanics" [8], or the GOP's cheap labor donors? [9]
