Ahmad Al Aliwi Alissa

Ahmad Al Aliwi Alissa is facing 10 counts of murder in the first degree and one count of attempted murder over the horrific attack at a King Soopers supermarket.

The president said the upper chamber needs to pass legislation approved by the House earlier this month, which would tighten gun laws including background checks.

"This is a real horror and terror for all of us," said Colorado Gov. Jared Polis, who said he has shopped at the same store where gunfire erupted on Monday.
