Chesser, who attempted to travel to Somalia to join Al Shabaab earlier this year, posted terrorist propaganda through a variety of Web sites, blogs and social networking sites.  In April 2010, Chesser – known online as Abu Talhah Al-Amrikee – threatened the creators of South Park for satirizing issues surrounding the depiction of the Prophet Muhammad.

Prior to his July 2010 arrest, Chesser also distributed original content, including a 25-page report on how to teach Western children the values of Jihad.  He also ran the Web site of Revolution Muslim (RM), a New York-based fringe anti-Semitic Muslim organization that justifies terrorist attacks and other forms of violence against non-Muslims.

Chesser pleaded guilty to providing material support to Al Shabaab, communicating threats and soliciting crimes of violence.
