The national gun control advocacy group “March for Our Lives” is making three stops in Iowa this week in Congressional districts represented by strong gun rights supporters.

Today’s stop will be outside the offices of Congressman Steve King, a staunch supporter of the second amendment and a critic of March for Our Lives. Organizer Kyrah Simon is from Parkland, Florida, where 17 people were killed during a high school shooting in February. Simon has a message for King.

“It’s really that the young people are not afraid, we’re not willing to back down to hatred,” Simon says. “Our voices are just as important, just as strong as his. We’re willing to make a change if he’s unwilling to do that.” Simon says a vigil will be held outside King’s office in Sioux City at noon today, as he’s a fervent supporter of gun rights and has sparred with the students on social media.

Simon says, “I think what’s amazing with the movement is that a few days after the shooting when everything was still raw, they had the courage, they had the bravery to go out and speak to the media, get their voices out, make an organization to implement change in our country.” They’re calling this the “Road to Change” bus tour. On Thursday, the group plans to hold an afternoon rally in Cedar Rapids and another event at Linn-Mar High School in Marion on Thursday night.
