Sen. Ted Cruz, R-Texas, has been spotlighted by the media for his willingness to criticize fellow Republicans, but the firebrand Republican has nothing but praise for his colleague Sen. Marco Rubio, R-Fla., as he pursues immigration reform.

“Marco has worked very, very hard to tackle the very difficult problem of how to fix our broken immigration system,” Cruz said in a interview with the Houston Chronicle. “And I think he has worked in good faith in a sincere desire to craft a solution as to how to approach immigration.”

Cruz added that Rubio was a “good friend” and “one of the strongest leaders on the national scene.”

In spite of his praise, Cruz maintained that giving illegal immigrants a pathway to citizenship was not something he supported.

“I have serious concerns about any legislation that would create a pathway to citizenship for those who are here illegally,” he explained. “I think doing so is inconsistent with the rule of law and is profoundly unfair to the millions of legal immigrants who have followed the rules and waited in line for years — and sometimes decades — to come here legally.”
