Steve King Accuses President Obama, Holder, And Napolitano Of 'Willful Ignorance' On Arizona Immigration Law (VIDEO)

AP/Huffington Post - An Iowa congressman whose invitation to headline a Colorado GOP fundraiser was rescinded after he made comments about President Barack Obama and race said Saturday that the president has injected race into the discussion about Arizona's new immigration law.

Republican Rep. Steve King spoke to about 100 people at a rally in the northern Colorado city of Loveland, accusing Obama and Attorney General Eric Holder and Homeland Security Secretary Janet Napolitano of "willful ignorance" on the details of Arizona's new immigration law.

The law, scheduled to take effect July 29, requires police to question people about their immigration status while enforcing other laws if there's reason to suspect someone is in the country illegally.

Obama administration officials have denounced it amid concerns of racial profiling. King said Saturday that Obama, Holder, and Napolitano have "contributed to misinformation" about the law.

Earlier this week, King was disinvited from Republican congressional candidate Cory Gardner's fundraiser and an event for the Tea Party of Northern Colorado after remarks he made Monday on G. Gordon Liddy's nationally syndicated radio talk show.

"The president has demonstrated that he has a default mechanism in him that breaks down the side of race on the side that favors the black person in the case of professor Gates and officer Crowley," King said in the radio interview.

He was alluding to last year's incident in which Obama commented on a white police officer's arrest of a black professor from Harvard University.

On Saturday, King said he was surprised by Gardner's reaction. No other Republican elected official has criticized his remarks, he said.

"When I look at the motive, I can see how they're rewarded for playing the race card because it solidifies their base," King said of the Obama administration in an interview before the rally. "So I don't say that it's necessarily racism, it's playing politics and using race to do so because it empowers them."
