REVEALED: Boulder shooter Ahmad Al-Issa expressed anti-Trump sentiment, reportedly had ISIS sympathies

Screenshots of Al-Issa's social media pages have also been obtained by The Post Millennial's Ian Miles Cheong, prior to the page being deleted. The screenshots show that Al-Issa was a practicing Muslim, aruging against Islamaphobia and for increased acceptance of refugees.

Al-Issa also shared anti-Trump content.

Al-Issa, 21, is in custody and has been accused of killing 10 people, including a police officer, after opening fire inside a King Soopers grocery store in Boulder, Colorado Monday afternoon. He has been charged with 10 counts of first degree murder.

Al-Issa, who was born in Syria, was shot in the leg by Boulder police and is currently in hospital, where police say he is in stable condition.

Boulder Police Chief Maris Herold identified the deceased officer as Eric Talley, 51, who has been called a hero by the police force. He was the father of seven children.
