Kean is the daughter of environmentalist and philanthropist Hamilton Fish Kean (1925–2016)[5] and the granddaughter of Congressman Robert Kean.[6] Her uncle is former New Jersey Governor Thomas Kean, and her cousin is New Jersey State Senator Thomas Kean Jr. The New Yorker reported in 2021 that she has "a modest family income" (income derived from inherited wealth).[7]
Kean worked as a photographer at the Lab of Ornithology at Cornell University.
After visiting Burma to interview political prisoners in the 1990s, she began working as an investigative journalist, producer, and on-air host at KPFA, a Berkeley, California-based radio station and the flagship station of the Pacifica Radio Network and for Flashpoints, a left-wing drive-time news program covering wrongful convictions, the death penalty, and other criminal-justice issues.[7]
According to Gideon Lewis-Kraus in April 2021, Kean has a photo of a purported UFO hanging on a wall behind her desk that was gifted to her by the Costa Rican government. This photo was taken by the Costa Rican National Geographic Institute in 1971 over Lake Cote and is considered by Kean to be "the finest image of a U.F.O. ever made public".[13] On 5 June 2023, Kean and writer Ralph Blumenthal reported that former United States Air Force officer and intelligence official David Grusch claimed that the United States has a secret UFO retrieval program with multiple vehicles of non-human origin as well as records of dead pilots in its possession.[14][15][16][17]
