Romney was critical of his rivals from both parties Tuesday.
SIOUX CITY, Iowa (CNN) – Republican presidential hopeful Mitt Romney took shots at his GOP and Democratic rivals Tuesday, accusing several of them of being soft on illegal immigration.
"There's a sanctuary state of mind that [New York Sen.] Hillary Clinton, and [former New York City] Mayor Giuliani, and [former Arkansas] Gov. Huckabee have," Romney said at a news conference. "They have provided - or support the idea of providing - tuition breaks to illegal aliens to institutions of higher learning, and that sanctuary state of mind flies in the face of the rule of law."
Clinton is seeking the Democratic presidential nomination, while Giuliani and Huckabee are challenging Romney for the GOP presidential nomination.
A Giuliani campaign spokeswoman fired back, and criticized Romney for his own track record on the issue of illegal immigration.
"Once again Presidential Trail Mitt Romney completely ignores the record of Governor Mitt Romney," Maria Comella, Giuliani's deputy communications, said in an email statement. "Under Governor Mitt Romney the number of illegal immigrants skyrocketed, while he recommended millions of dollars in state aid to numerous sanctuary cities and to companies employing illegal immigrants, not to mention the illegals working on his own lawn."
