A U.S. judge has agreed to review the government's decision to repatriate 15 Cuban migrants after they reached an abandoned bridge in the Florida Keys.

U.S. District Judge Federico Moreno Thursday questioned the government's reasoning for sending back the migrants earlier this week.

Moreno called the bridge "as American as apple pie" - an expression common in the U.S. to indicate something is certainly American - even though it does not connect to dry land.

A Cuban advocacy group had filed a legal complaint on behalf of the repatriated Cubans.

The U.S. employs a "wet foot, dry foot" policy for illegal Cuban immigrants. The policy allows Cuban refugees who reach U.S. soil to stay in the United States, while those intercepted at sea are sent back home.
