Senate Majority Leader Mitch McConnell on Tuesday called the violence that has erupted in Baltimore over the death of Freddie Gray “regretful,” saying he hopes the criminal investigations conclude quickly.

“Obviously our hearts go out to those who’ve been injured and the other activities that have occurred there that are so regretful,” McConnell said. “I hope the investigation into illegal behavior will be concluded soon and those who’ve been engaged in criminal behavior would be promptly pursued and charged.”
