U.S. Capitol Police increased security for Klobuchar and Smith following the attacks, which occurred early Saturday morning. Minnesota's entire congressional delegation, both Republicans and Democrats, released a joint statement condemning the killings.

The man suspected of shooting two Minnesota lawmakers, killing one of them, has been taken into custody, a law enforcement official said. Vance Boelter was arrested Sunday evening. The arrest was confirmed to The Associated Press by a law enforcement official who not publicly discuss details of the ongoing investigation and spoke to AP on condition of anonymity.
