The gunman, who was shot dead at the scene by police after killing eight people, including children, was named as 33-year-old Mauricio Garcia.
President Joe Biden called on Republican members of Congress to pass gun control bills in the wake of yet another mass shooting that left nine people dead, including the gunman, at a Texas mall on Saturday.
The shooter was named on Sunday as 33-year-old Mauricio Garcia, according to two senior law enforcement officials who spoke to NBC News.
The US president renewed calls for a ban on assault weapons and high-capacity magazines, as well as to enact universal background checks and end immunity for gun manufacturers.
There is little chance that the Republican-controlled House or the narrowly Democratic Senate would pass such legislation, despite polls showing most Americans support background checks.
The president said the assailant wore tactical gear and was armed with an AR-15-style assault weapon.
