US working with Egypt to lift travel ban on NGO workers 'in merest days'

The State Department said Thursday it is "very actively involved" in working with the Egyptian government to lift the travel restrictions on American citizens working with non-governmental organizations (NGOs) in Egypt.

State Department spokesperson Victoria Nuland said, "We are urging the government of Egypt to lift these restrictions immediately and allow folks to come home as soon as possible. And we are hopeful that this issue can be resolved in merest days."

There are four or five specific cases of Americans who have been barred from leaving Egypt that the State Department is currently working on. Nuland would not confirm if Sam LaHood is one of those cases because of privacy concerns. International Republican Institute (IRI), the NGO that LaHood works for, however, confirmed that for NBC News on Wednesday night. LaHood's father is U.S. Transportation Secretary Ray LaHood.

The Americans who have unsuccessfully tried to leave Egypt are not being detained, and they are in possession of their passports.
