Under FBI surveillance
At the same time he was selling U.S. secrets to the Soviet Union, former FBI special agent Robert Hanssen was a key supervisor in a 1980s domestic-spying program questioning the loyalty of American citizens and monitoring their activities, FBI documents have shown.
Under this program, federal agents filed reports on teachers, clerics and political activists who primarily were affiliated with liberal causes.
For instance, one document included is the entire list of U.S. delegates to the 1987 World Congress of Women convention in Moscow. They ranged from the likes of former Texas legislator and human rights activist Frances "Sissy" Farenthold to the Rev. Nan Brown, a Baptist minister from Palmyra, Va. Brown said she went to Moscow simply because she wanted to look at the Soviet education system.
"I'm astounded, really," she said when informed that her name was in the files. "I only went because I wanted to go to the conference." 
In Geneva with Gorbachev
A vocal opponent of the Vietnam War, Bill Aleshire applied for, and got, conscientious objector status, an issue that he says caused more than a little conflict with his military officer father. Part of the work he did as community service in lieu of military service was to work in the Texas Legislature. He worked as a volunteer for The Dirty 30, a group of reformist legislators that included Reps. Sissy Farenthold and Lloyd Doggett, among others.
