The Wall Street Journal editorial has the following information.

Our own “confidence” is not heightened by the fact that the NIE’s main authors include three former State Department officials with previous reputations as “hyper-partisan anti-Bush officials,” according to an intelligence source. They are Tom Fingar, formerly of the State Department’s Bureau of Intelligence and Research; Vann Van Diepen, the National Intelligence Officer for WMD; and Kenneth Brill, the former U.S. Ambassador to the International Atomic Energy Agency (IAEA).

For a flavor of their political outlook, former Bush Administration antiproliferation official John Bolton recalls in his recent memoir that then-Deputy Secretary of State Richard Armitage “described Brill’s efforts in Vienna, or lack thereof, as ‘bull–.'” Mr. Brill was “retired” from the State Department by Colin Powell before being rehired, over considerable internal and public protest, as head of the National Counter-Proliferation Center by then-National Intelligence Director John Negroponte.
