Obama Heads to Tucson on Wednesday

A White House official said Monday that President Obama will travel Wednesday to Tucson, Arizona, the scene of the shooting rampage that left six people dead and critically injured Congresswoman Gabrielle Giffords. The president is navigating treacherous territory, trying to find a balance of timing and tone in addressing Saturday's shooting. He led a moment of silence on the South Lawn in honor of the victims of the shooting. The president said he has been “spending a lot of time just thinking about the families,” and said the whole nation is “ grieving and in shock.” Obama is likely to give a speech about tolerance, a message that could also pervade his upcoming State of the Union speech.
