Republican National Committee Chairman Reince Priebus on Thursday forcefully condemned "self-deportation," the policy of making life for undocumented immigrants so difficult that they voluntarily leave the United States.
"Using the word 'self-deportation' -- it's a horrific comment to make," the RNC chairman was quoted as saying in Business Insider. "I don't think it has anything to do with our party. When someone makes those comments, obviously, it hurts us."
Former Republican Party presidential nominee Mitt Romney used the phrase in a Republican debate in 2012 when asked about his approach to immigration. The phrase was repeatedly attacked by the Obama campaign, and Republican Newt Gingrich said it was an inhumane and unrealistic approach to dealing with illegal immigration.

Chairman Priebus's assertion that efforts to get people to comply with U.S. immigration laws are 'horrific' further erodes his credibility as the leader of a national political party.

FAIR and its friends must be feeling pretty lonely right now.
