US lawmakers call for investigation into death of activist Aaron Swartz

A group of US lawmakers demands that judicial officials answer questions about the death of an Internet activist who'd criticized President Obama's "kill list."

Eight lawmakers from both the Democratic and Republican parties are asking Attorney General Eric Holder to come clean on why Aaron Swartz killed himself last year. They say Swartz faced an aggressive prosecution. The activist committed suicide in his apartment a year ago. At the time, he was awaiting trial for downloading millions of academic documents from an online database. Swartz was a computer programmer, an internet activist and a hacker who supported freedom of expression. He was a critic of the government's secret process to kill or capture terrorists.
