The defense said it received an email from the government that mentioned the FBI was investigating Mateen.
The email went on to say that from January 2005 to June 2016, the FBI was using Mateen’s father as a confidential informant.
But following the Pulse attack, FBI agents searched his home and found receipts showing he transferred money to Turkey and Afghanistan in March and June before the Pulse attack.
The government said an anonymous tip revealed that Seddique Mateen wanted to raise up to $100,000 to help toward an attack against the government in Pakistan.
Defense attorneys said that receiving the information after prosecutors rested their case, is unfair to Salman.
“That is information that should have been disclosed. It raises a lot of questions about his role in the prior investigations of Omar Mateen himself. The FBI investigated Omar Mateen in 2013 and closed the file,” community activist Ahmed Bedier said. A former friend of Mateen, who the public knows as Nemo, testified Monday.
Nemo said he was shocked and horrified when he learned that Mateen used him as an excuse the night of the attack.
However, Nemo testified that he was not surprised because Mateen always used him as an excuse when he was “running around” on his wife.
Two women who had a relationship with Mateen also testified Monday. One woman said she met Mateen online, and that they had a physical relationship.
Two of Salman’s childhood friends testified that she was a peaceful person.
Salman's attorneys are revisiting statements made by key government witness, polygraph examiner, Ricardo Enriquez.
According to Enriquez, Salman told him that Omar Mateen left home with a gun placed in a holster on his hip before the attack.
The government then used those comments as evidence.
But defense attorneys said the government knew Mateen never left his home with his work gun holstered on his hip because they later found the holster while searching his home after the attack.
Salman faces life in prison if convicted.
