A moment of silence was observed Monday across the country as well aboard the International Space Station. The commander of the space station is Scott Kelly, Giffords’ brother-in-law. He sent this message from space.

Commander Scott Kelly: “As I look out the window, I see a very beautiful planet that seems very inviting and peaceful. Unfortunately, it is not. These days we’re constantly reminded of the unspeakable acts of violence and damage we can inflict upon one another, not just with our actions, but also with our irresponsible words.”

It was revealed yesterday that less than 24 hours before she was shot, Rep. Gabrielle Giffords wrote a letter to a prominent Kentucky Republican expressing a desire to find ways to tone down rhetoric and partisanship.
