New York Mayor Michael Bloomberg on Wednesday said the costs of hosting the federal trials of Khalid Sheikh Mohammed and other suspected September 11 plotters would top $200 million annually and formally requested that Washington cover the costs."New York's financial resources are in short supply, and we have been forced to reduce our Police Department's headcount," Bloomberg wrote in a letter to White House Budget Director Peter Orszag dated January 5 and released to media on Wednesday."Securing the trial will require us to pull existing personnel from crime prevention efforts around the city and require significant overtime expenses," the mayor wrote."As 9/11 was an attack on the entire nation, we need the federal government to shoulder the significant costs we will incur and ease this burden."
