President Barack Obama will travel to Tucson for a memorial service on Wednesday. It will be an important moment in his presidency, and his words will be under scrutiny.
Few could criticise him so far for his reaction to the shooting. He stood alongside the First Lady on the White House lawn and led the nation in a minute's silence for those killed and wounded in Arizona. He can't afford to be accused of exploiting the tragedy for political gain and speaking afterwards instead attempted to be inspirational.
He said those in the crowd at the scene showed heroism: "Part of what I think that speaks to is the best of America, even in the face of such mindless violence."
He continued: "But I think it's going to be important, I think, for the country as a whole, as well as the people of Arizona, to feel as if we are speaking directly to our sense of loss, but also speaking to our hopes for the future and how out of this tragedy we can come together as a stronger nation."
Of course, whatever the president does is political, and remaining above the political fray and not entering the national debate about the role of harsh language in politics, is in itself a piece of positioning. He, as president, wants to been seen as a healer, and to recapture something he has lost since his election: the mantle of someone who can unify rather than divide.
