Former Republican congressional candidate Jesse Kelly is canceling all events scheduled for this weekend.

Kelly, who ran against U.S. Congresswoman Gabrielle Giffords in the November general election, had what he called an “exciting announcement” scheduled for this coming Saturday, emceed by radio personality Jon Justice and expected to provide more details on future political plans.

Kelly released a statement following Saturday’s shooting that claimed six lives and left Giffords in critical condition while recovering from a gunshot wound to the left side of her head.

“In the wake of this stunning tragedy, my prayers are with Rep. Giffords, her husband Mark and the rest of her family,” Kelly said. “May God’s strength comfort her as we pray together for her recovery.  We mourn for those who lost their lives in this horrible act.

Senseless acts of violence such as this have absolutely no place in American politics.”
