Hillary Clinton, who was serving as junior U.S. senator for New York when the September 11 attacks occurred, has published an essay in The Atlantic drawing personal and political lessons from the aftermath of the attacks. Writing under the title "What the Aftermath of 9/11 Taught Me," Clinton argues that governments must be transparent with citizens in moments of crisis, citing the failure of federal officials to fully disclose dangerous air quality at Ground Zero in the weeks and months after the attacks. Clinton, who visited the site the day after the attacks and later learned that White House officials had directed the Environmental Protection Agency to downplay the presence of deadly toxins in the air, said the episode remains one of the angriest moments of her public life — and warned that health consequences for those exposed are still emerging, noting the recent diagnosis of former New York Governor George Pataki with a restrictive airway disease linked to his 9/11 exposure.
