Retired two-star Navy. Adm. Joe Sestak is the highest ranking — and perhaps, least known — veteran who is trying to clinch the Democratic nomination for president in 2020.
Sestak has decades of military experience, but he is not getting nearly as much media attention as fellow veterans Pete Buttigieg and Rep. Tulsi Gabbard (D-Hawaii). Another veteran, Rep. Seth Moulton (D-Mass.) has dropped out of the race.
