Megan Rapinoe called on Americans to urge their congressional representatives to change what she described as "insane" gun-control laws or vote them out of office.
Rapinoe said Wednesday "our whole heart goes out to everyone in Texas" after 19 children and two teachers were killed in a shooting at Robb Elementary School on Tuesday, per Cesar Brioso of USA Today.
The massacre came less than two weeks after 10 people were killed in a racist attack on a grocery store in Buffalo.
"We're living in an insane country when it comes to gun control and gun laws," Rapinoe said.
