White House press secretary, Josh Earnest, fielded questions yesterday about the Yemeni collapse from ABC reporter Jonathan Karl and didn't back down from claiming Yemen is a model for counterterrorism efforts. The Yemeni government has officially collapsed and the president has fled the country as Houthi rebels, backed by Iran, have taken the countries third largest city. Saudi Arabia has reportedly started a military mission in Yemen to prevent the chaos from spilling over the border.
