NEW YORK (REUTERS) - A US judge on Monday ordered the unsealing of the application used to obtain a search warrant that allowed the FBI to gain access to emails related to Democratic nominee Hillary Clinton's private server shortly before the Nov 8 presidential election.

U.S. District Judge Kevin Castel in Manhattan directed the release by Tuesday of redacted materials used to obtain a search warrant after Federal Bureau of Investigation Director James Comey informed Congress of newly discovered emails on Oct 28.
