Rep. Steve King (R-IA), who has been outspoken about his opposition to immigration reform, on Saturday indicated that Republican leaders support immigration reform because large donors like the U.S. Chamber of Commerce are pushing them to.

“It seems as though there are some deep pockets outside the Congress and across the country that seem to be the only voices that line up with the Republican leadership in the House on immigration,” he said on the Tea Party News Network’s “The Capitol Hill Show.”

“I’m happy to promote business, but I’m not one of those folks that’s going to be directed by billionaires with big checkbooks and I think that’s part of the division we have today in the Republican congress.”

Republican House leaders unveiled a draft of their principles on immigration reform in January
