Donald Trump’s real estate organization rented New York office space from 1998 to 2003 to an Iranian bank that U.S. authorities have linked to terrorist groups and Iran’s nuclear program.

Trump inherited Bank Melli, one of Iran’s largest state-controlled banks, as a tenant when he purchased the General Motors Building on Fifth Avenue in Manhattan, according to public records reviewed by the International Consortium of Investigative Journalists and the Center for Public Integrity. The Trump Organization kept the bank on as a tenant for four more years after the U.S. Treasury Department designated Bank Melli in 1999 as being controlled by the Iranian government.

U.S. officials later alleged that Bank Melli had been used to obtain sensitive materials for Iran’s nuclear program. U.S. authorities also alleged that the bank had been used between 2002 and 2006 to funnel money to a unit of the Iranian Revolutionary Guard that has sponsored terrorist attacks — a period that overlapped with the time the bank rented office space from Trump.
