Heineman is scheduled to leave Thursday for this year's National Governor's Association conference. The gathering for Democratic and Republican governors runs through Sunday.
Organizers say the event will focus on education, workforce development, health care, veterans and jobs.
The National Governors Association represents the governors of all 50 U.S. states and five U.S. territories. Heineman served as the group's chairman from July 2011 through July 2012. He was the first Nebraska governor to hold the title in 50 years.
