Greg Brock is a reporter for the New York Times.
A leak on the International Space Station leaves three astronauts (2 Americans and a Russian) at risk of dying in space. The U.S. claims it's unable to rescue the astronauts; however Brock reports that the U.S. actually can save them by using a secret military space shuttle.
The story sparks a major criminal investigation at the White House to find out who gave him classified information about the military shuttle; whoever revealed the information committed a felony. Brock is sent to prison after refusing to name his source. ("The Mommy Problem")
