Cong Thanh Do is back in the U.S.A. after spending 38 in jail in Vietnam.
"Dos arrest exposed a double life he had led for seven years. By day, he was an engineer at Applied Materials. By night, he was an online freedom fighter who wrote political essays under a pen name, Tran Nam, who pushed for an end to Vietnams one-party communist system.
He and his wife had fled Vietnam by boat, arriving in the United States as political refugees in 1982. Even as he settled into the routines of family life, fathering three children and starting a bakery on the side, Do never gave up on hopes of helping reform his native country.
I have a very nice, comfortable life here in the United States. But a part of me is always in Vietnam, said Do, 47. Ive always wanted to do something for Vietnam, so the people can enjoy what I do: democracy."
