An investigation by the New York City Comptroller's office in October 2016 showed that Trump and/or the Donald Trump Foundation may have failed to honor at least one pledge to charities established to provide relief for victims of the September 11, 2001, terrorist attacks. Trump had made a pledge of $10,000 to the Twin Towers Fund on "The Howard Stern Show" in late September 2001. The Twin Towers Fund, later administered as part of the New York City Public and Private Initiative, was created by then-New York City Mayor Rudolph Giuliani "to benefit the families of firefighters and police officers who died in the attacks."
