A federal commission investigating the Sept. 11 attacks has voted to subpoena documents New York has failed to hand over related to the city’s response to the World Trade Center attack. The commission said Thursday it is seeking tapes and transcripts of 911 calls and transcripts of hundreds of interviews of firefighters conducted by the Fire Department after the 2001 attacks. The commission is investigating the nation’s preparedness before Sept. 11 and its response to the attacks, and will make recommendations for guarding against similar disasters. The bipartisan panel, formed by Congress and headed by former New Jersey Gov.
