The Obama administration is "reprogramming" some funds to Egypt while a review is underway -- in effect, temporarily holding up some military aid to the country, a U.S. official said.

A spokesman for Sen. Patrick Leahy, David Carle, confirmed to CNN his office has been told the aid has been halted. Leahy, a Vermont Democrat, is chairman of the Appropriations State and Foreign Operations Subcommittee.
