She is accused of helping Mateen plan and carry out the June 12 attack at Pulse nightclub that killed 49 people and injured 53 others.
Salman’s attorneys argued that she was not a danger to the public and her family members were willing to put up their homes as collateral for her release.
She was also going to be required to wear a GPS tracking device.
Prosecutors claimed that Salman knew what her husband was planning and accompanied him on “scouting” trips to several areas, including Pulse nightclub.
In Friday’s order, the judge noted a text message Salman sent Mateen could be construed in different ways.
Texting her husband after receiving a phone call from her mother-in-law asking why Mateen had not come over for Ramadan, Salman asked, “Where are you?”
Since she had said she knew he was going to a friend’s home that evening, the ruling judge pointed out that the question could mean she truly did not know where he was, or that she was asking which target he had attacked.
Salman is accused of accompanying Mateen to City Place, Disney Springs and Pulse nightclub to scout for an attack target.
The judge also reasoned that since members of Salman’s family own property in the West Bank, there was no guarantee that the Palestinian National Authority “would comply with extradition requests from the United States should defendant Salman flee to take up residence in Palestine.”
