Mexico has been quiet in recent years on the US immigration debate after former President Vicente Fox's vocal push for US reform prompted criticism.
Bill O'Reilly announced his support for the immigration reform bill on his Fox News show Thursday night, in light of a border-security compromise that has been struck.
Sens. Michael Bennet (D) and Jeff Flake (R), two of the Gang of Eight immigration reformers, said Wednesday there's room to amend the immigration reform bill to include some things conservatives want without sacrificing Democratic votes. Other 'gang' members are more worried.
