The media venture created by entrepreneur Pierre Omidyar said Monday it was establishing a fund to help defend journalists in cases involving freedom of the press. First Look Media said its first grant would be in support of the appeal in Britain of David Miranda, the partner of investigative journalist Glenn Greenwald. Miranda, a Brazilian citizen, was held for nine hours at Londons Heathrow Airport on August 18 while police questioned him about the material leaked by former US National Security Agency (NSA) contractor Edward Snowden. First Look general counsel Lynn Oberlander said the new fund would provide legal support to journalists and others engaged in contests where freedom of the press is at stake in the US and abroad.
