which would later become Mobil Oil and which then merged to become part of ExxonMobil. But the Jennings family denies any connection, said a grandson, Brewster Jennings, a real estate investor in Durango, Colorado. He said that since the firm was named as a CIA front he's heard from many friends and family members who "find tremendous humor in all this." Physical location According to research published by Pincus and Allen, "The phone number in the Dun & Bradstreet listing is not in service and the property manager at the address listed said there is no such company at the property, although records from 2000 were not available." 101 Arch Street is a 21-story "tower finished in 1988 at the corner of Summer and Arch streets with 405,511 square feet (37.6257 square meters) of office space, then housing the upscale Dakota's restaurant, since succeeded by Vinalia. Many commuters pass through the building as they exit the Downtown Crossing subway station. 101 Arch was sold in 2003 to CB Richard Ellis Investors of Los Angeles for an estimated $90 million." Nuclear investigation According to The Sunday Times and its main source Sibel Edmonds, Brewster Jennings & Associates was used by the CIA to investigate an alleged foreign intelligence ring, including Pakistan's ISI, which was attempting to recruit moles to obtain U.S. nuclear secrets. A parallel investigation was being run by the FBI. The American-Turkish Council put Brewster Jennings in contact with a number of Turkish agents involved in the ring, but who claimed to be conducting research in alternative energy sources. The Turkish agents were on the verge of hiring the firm for consultation when a senior US State Department official tipped them off, leading them to break off the relationship and warn the ISI and others of the front company. The State Department officially denies this. This official was later identified as Marc Grossman, the former Under Secretary of State for Political Affairs from 2001-2005, both under sworn testimony by Edmonds and by other sources.
