President Joe Biden and First Lady Dr. Jill Biden visited Uvalde on Sunday to offer comfort to a community gripped by grief after a deadly mass shooting at an elementary school.

The shooting happened Tuesday at Robb Elementary School when an 18-year-old gunman walked in and opened fire with an AR-style rifle, claiming the lives of 19 children and two teachers.

The Bidens stopped in San Antonio briefly and were welcomed at Kelly Field by San Antonio Mayor Ron Nirenberg before boarding Marine One and heading to Uvalde. After they arrived, the pair was greeted by other community and religious leaders and met with victim’s families.

A few hours into the Biden visit, the Justice Department announced that it will review the law enforcement response to the shooting, which has already received pushback due to contradictory information from authorities.

1:30 p.m. - Bidens leave Mass at Sacred Heart Catholic Church, meet with shooting victims’ families

5:30 p.m. - The Bidens depart from Uvalde, San Antonio

The visit will come less than two weeks when the Bidens traveled to Buffalo on May 17 to mourn with grieving families who lost loved ones in a mass shooting at a supermarket. Ten people, all of them Black, were gunned down by a man who espoused the racist “replacement theory.”

Biden’s reaction to the shooting in Uvalde has been searing, as he refocuses his presidency on one of the greatest political challenges of his career — the long fight for gun control.

“Where’s the backbone, where’s the courage to stand up to a very powerful lobby?” Biden said Wednesday as he called for Congress to pass new laws. ”When in God’s name are we going to stand up to the gun lobby? Why are we willing to live with this carnage? Why do we keep letting this happen?”

But if Thursday is any indication, Republicans don’t plan to budge. An attempt by Democrats to respond to the two recent mass shootings failed in the Senate as Republicans blocked a domestic terrorism bill that would have opened debate on difficult questions surrounding hate crimes and gun safety.
