Jury selection is underway for the trial of the Pulse Orlando nightclub shooter's widow, Noor Salman.
Salman's trial will be held in federal court in Orlando.
The case hinges on whether or not Salman helped Omar Mateen plan the 2016 attack at Pulse nightclub that killed 49 people. Mateen called 911 from the club to pledge his allegiance to the Islamic State. He died in a shootout with police.
Salman faces charges of aiding the support of a foreign terrorist organization resulting in death and obstruction of justice.
Prosecutors say Salman knew of her husband's plans. She denies the claim.
Though he's not on trial, the government has to prove Mateen killed in support of the Islamic State.
