On the run from South Sudan’s government

One of the most outspoken critics of  South Sudan’s government, Peter Biar Ajak, has arrived in the US seeking refuge. Ajak says he’s fleeing because South Sudan’s government wants to abduct or kill him. The government in Juba denies the charge. Ajak speaks with The World’s Marco Werman about why he’s on the run and his efforts to ignite a pro-democracy movement in South Sudan.
