Lebowitz is an attorney in the field of military law and specializes in military free speech where he served as defense counsel in a number of cases where uniformed personnel faced discipline for speech-related activities. Lebowitz has worked on trials involving military freedom and expression. He lectures on the subject and is asked to serve as a media resource on the impact technology continues to play in the field of military free speech. More recently, he has written on the subject of war crimes and national security, and has served as a war crimes prosecutor at Guantanamo Bay.
Lebowitz is a founder of the Modern Whig Party, an organization originally created in 2008 as an advocacy forum for military families and veterans. This centrist organization professes to offer common-sense approaches to government, rather than ideology. In March 2010, the Modern Whig Party was named by TIME Magazine as among the "top 10 most popular political movements worldwide." Since 2009, upon entering government service, Lebowitz ceased activity with the organization.
