Matthew McConaughey said Tuesday that "action must be taken" after a shooting at an elementary school in his hometown of Uvalde, Texas, left at least 19 children and two teachers dead. 

"Once again we have tragically proven that we are failing to be responsible for the rights our freedoms grant us," the "Dallas Buyers Club" actor wrote in a statement on his social media pages.

He said every American needs to ask, "What is it that we truly value? How do we repair the problem? What small sacrifices can we individually take today, to preserve a healthier and safer nation, state and neighborhood tomorrow?"

He said that Americans can’t accept mass shootings as the status quo.

"As Americans, Texans, mother and fathers, it’s time we re-evaluate, and renegotiate our wants from our needs," he continued. "We have to rearrange our values and find a common ground above this devastating American reality that has tragically become our children’s issue."

He called it an "epidemic we can control," adding that whatever way people lean politically, "we all know we can do better."

Tuesday's shooting is the deadliest school shooting since Sandy Hook Elementary in Connecticut in 2012.
