A Garland, TX police officer will be honored with a Public Safety Officer Medal of Valor by President Barack Obama at the White House Monday morning.

Officer Gregory Stevens is credited with gunning down Elton Simpson and Nadir Soofi as they attempted to carry out a mass shooting at an anti-Islamic art contest in Garland last May. President Obama will present him with the Medal of Valor during a ceremony in the East Room around 11:00 AM.

The two suspects planned to open fire inside Garland's Curtis Culwell Center, where a group known as The American Freedom Defense Initiative was hosting a Muhammad Art Exhibit in protest of the attack on the offices of satirical French magazine Charlie Hebdo in January of 2015.

The two men shot and wounded a Garland ISD officer, but were themselves shot and killed by Officer Stevens before they could enter the buildint to carry out their attack.

Investigators later learned that Simpson and Soofi planned the attack on behalf of the Islamic State, which later claimed responsibility.

In June of 2015, a third conspirator, Abdul Malik Abdul Kareem, was indicted by a federal grand jury on felony charges of conspiracy, lying to federal agents, and interstate transportation of firearms with the intent to commit a felony. He confirmed that the attack was motivated by ISIS.
