On Sunday, the American Embassy in Cairo offered to shelter American citizens barred from leaving the country after the Egyptian government instituted a travel ban on 17 American citizens working for NGOs within the country. Sam LaHood, son of Transportation Secretary Ray LaHood, is among  the Americans stuck in Cairo. The American Embassy's need to shelter American citizens in a once-friendly nation symbolizes a serious rift in U.S.—Egypt relations. Michael Posner is the Assistant Secretary for Democracy, Human Rights and Labor for the U.S. State Department.
