Washington: The heads of five House committees are pressing President Barack Obama about a comprehensive policy for handling terror suspects after the US questioned a Somali man for two months aboard a Navy ship and then transferred him to New York to stand trial in a civilian court.

The lawmakers, including Armed Services Committee Chairman Howard "Buck" McKeon and Intelligence head Mike Rogers, sent a letter to Obama on Wednesday.

At issue is whether the administration went against Congress' wishes that military commissions at the US prison at Guantanamo Bay, Cuba, handle the trials of terrorism suspects.

Ahmed Abdul kadir Warsame was indicted on federal charges in New York earlier this month.
