[2] When the civil war ended, Lobong was appointed Chief of the National Intelligence and Security Service for the Southern Sector of South Sudan.
It was said that Lobong failed to gain support for his candidacy from the chiefs in the State Conference in Chukudum in June 2005 due to dissatisfaction over his failure to prevent Toposa of Namorunyang from raiding and destabilizing the Lauro and Lotukei areas of Budi County.
In October 2009, responding to the recent wave of ethnic violence, Lobong called for the government to take harsh measures to deter others from causing problems.
[5] Lobong took his oath of office on 19 May 2010 in a ceremony at the Eastern Equatoria State Legislative Assembly Hall in Torit, taking over from caretaker Governor Johnson Juma Okot.
[7] After the successful referendum in January 2011 in which 99.95% of votes were for south Sudan secession, Lobong was visited by a delegation of women from all eight counties of Eastern Equatoria.
He recognized the great contribution that women had made during the civil war and subsequent struggle leading up to the referendum, and called on them to help build peaceful ties between the different ethnic groups in the state.
[13] During the July 2011 independence celebrations, Lobong urged citizens to play an active role in suppressing cattle rustling, which he described as the biggest challenge to security in South Sudan, one of the poorest countries in the world.
