Walorski has represented Indiana’s District 2 since 2013. She earned the Republican nomination for reelection in May and was slated to defend her congressional seat against Democratic challenger Paul Steury in November’s midterm elections.

“I am shocked and saddened by the news of Representative Walorski’s passing. Words are hard to come by in moments like these, especially when such a tragedy happens so suddenly,” Steury wrote in a statement shared on Twitter. “Rep. Walorski committed her life to service. But having met Jackie as both a constituent and on the campaign trail, it was her kindness, even to those who disagreed with her, that stuck out the most.”

“The daughter of a firefighter, small business owner, and Air Force veteran, Jackie was raised with the Hoosier values of hard work, determination, and public service,” the bio reads. “She brings these values to her service to the 2nd District of Indiana. Jackie and Dean, a Mishawaka school teacher, live in Jimtown.”

Fellow Republican Rep. Adam Kinzinger said in a Twitter post Wednesday, “My heart is heavy, and i don’t have the words. But all I can say is prayers for her family. She was a good and honorable public servant.”
