The Romney campaign has once again attracted criticism for its approach to immigration in light of Romney’s endorsement of immigration hardliner Rep. Steve King (R-IA) Friday. Romney gave King his full support at the event, telling his audience, “This man needs to be your congressman again…I want him as my partner in Washington D.C.” The Obama campaign criticized the endorsement as a failure on Romney’s part to check one of “the most strident voices in his party.”

King is a conservative congressman from Iowa who has taken tough anti-illegal immigration stances, including suggesting an electrified fence along the Mexican border. He has also attracted attention for a controversial comment earlier this year in which he compared immigration policy to picking the best dogs in a litter. King defended his comments in a later interview, saying “I’ve long used these examples. We’ve skimmed the cream of the crop off every civilization on the planet.” King, who sits on the House Subcommittee on Immigration, also favors making English the official language of the United States.

Following Romney’s endorsement of King, the Democratic National Committee posted a Web video that concluded, “Mitt Romney & Steve King. Partners in extremism.”
