Noor Salman's lawyers file new motion about Pulse shooter's infidelity

ORLANDO, Fla. – Lawyers for the wife of the Pulse Nightclub shooter have filed a new motion in court, arguing Omar Mateen's deceit will clear her name. 

Noor Salman's attorneys want the jury to hear from a friend of Mateen, who is willing to testify about the gunman's alleged infidelity.

Attorneys say that witness will tell jurors how Mateen would sneak out of his home to meet other women both online and through an escort service. 

Salman's lawyers also want to introduce text messages between Mateen and his wife from the morning of the Pulse shooting. They say it will show that Salman didn't know where her husband was or what he was doing. 

Salman is charged with helping her husband in the attack last year that left 49 people dead. 

Prosecutors have not responded to the new motion.
