A Georgia man spent hours watching videos showing Taliban speeches and showing how to make bombs while discussing possible targets for a domestic terrorist attack, a former friend testified Tuesday.

Omer Kamal testified against Ehsanul Islam Sadequee, who is charged with providing material support to terrorists and conspiring to help the Lashkar-e-Taiba terrorist group. Prosecutors say Sadequee and Sayid Haris Ahmed scoped out possible targets in Washington, D.C. and that they went to Canada to conspire with other Lashkar supporters.

Ahmed was found guilty in a bench trial June 10 and now has agreed to testify for the prosecution against Sadequee.

On Tuesday, the Atlanta Journal-Constitution reports, former friend Omer Kamal testified that Ahmed and Sadequee were "contemplating going to any theater of combat to participate in violent jihad." The plans grew so intense that Kamal said he wrote his friends a note saying he wanted nothing to do with it.

Sadequee is representing himself in the trial. During his opening statement, Sadequee passed off his comments as "just empty talk" and claimed "There was no plan."

During Ahmed's trial, prosecutors showed rough surveillance videos Sadequee and Ahmed shot of the Pentagon and the U.S. Capitol.
