Early Friday morning, President Barack Obama said that America is “horrified” and offering condolences on Friday by what appears to be a planned sniper shooting targeting police officers in Dallas, and he said there is no justification for the violence.

In honor of the victims of the attack, the President has ordered all public building and grounds, all military posts and naval stations, and at the White House to fly the American flag at half-staff until sunset on July 12.

House Speaker Paul Ryan says anger over the police shootings in Dallas must not be allowed to harden the nation’s divisions.

Speaking Friday on the House Floor, Ryan said that “justice will be done.” He says it’s been a “long month for America” and that the nation has seen terrible and senseless things. But he says that in debating how to respond, “let’s not lose sight of the values that unite us, our common humanity.”

Ryan says: “A few perpetrators of evil do not represent us; they do not control us.”

House Minority Leader Nancy Pelosi took the floor after Ryan, joining in his expression of grief and thanking Dallas police officers for their service.

Pelosi says: “Justice will be done, justice must be done. Also mercy must be done.”
