The brother of a Sandy Hook Elementary School shooting victim is challenging a state senator for his seat.

JT Lewis, the 19-year-old brother of Jesse Lewis, announced his candidacy for the 28th state Senate district, currently represented by Republican Tony Hwang, in a video posted to Twitter Monday.

In the video, Lewis said he and his mom called Hwang, who was then a state representative, after the 2012 shooting but never heard back from Hwang. Hwang was elected to the Senate in 2015.

“The little boy who just wanted someone to hear his mom’s call for help is grown up,” Lewis said in the video. Police have said Lewis’ brother, Jesse, who was one of 20 first graders killed in the Dec. 12, 2014 shooting the Newtown school, may have saved several lives when he yelled for his fellow students to “run” during a break in the shooter’s fire.

“I believe that inside every one of us is that same innate courage and to honor Jesse, I’ve decided to be courageous enough to run for state senate in my home state.”

Lewis, a Republican from Newtown, just completed his first year at the University of Connecticut.

The election will take place in November 2020. The 28th Senate District stretches from Newtown to Fairfield and includes Weston, Easton and part of Westport.; 203-842-2563; @kaitlynkrasselt
