The brother of a Phoenix man, who pledged allegiance to ISIS, testified Wednesday in Abdul Kareem's trial.
The FBI says Kareem helped Elton Simpson and Nadir Soofi plan their attack at an anti-Mohhammed event in Garland, Texas.
Simpson and Soofi were killed during the shootout with police. Kareem was arrested about a month later in June.
In court, Nadir Soofi’s younger brother Ali, said he met Kareem when he lived with Nadir in Phoenix.
Ali testified he lived with his brother Nadir and Simpson from 2014-2015. He said Kareem would come over often and he was very vocal about his support for ISIS. Him and his brother, Kareem and Simpson would watch ISIS videos almost every day.
Ali recalled one ISIS video in particular, where a man was beheaded. Kareem tried to get Ali to convert back to Islam.
“In general I was an outcast in that group,” said Ali.
Ali moved out in April 2015, about a month before the foiled Texas attack.
Ali testified Simpson would communicate with Mohamed Abdullah Hassan via twitter.
After the Charlie Hebdo attack, his brother, Kareem and Simpson became more extreme.
Hassan, also known online as “Miski” is the Minnesota man, suspected of recruiting impressionable young men for terror groups like ISIS.
Authorities say “Miski” is linked to at least one domestic terror attack in the US.
It’s believe “Miski” left Minnesota to join a terror group in Somalia in 2007.
However, this past December, “Miski” surrendered to law enforcement in Somalia.
