Ash-covered shoes and a president in crisis: A Reuters reporter remembers 9/11

Iconic moment: Bush was reading to schoolchildren in Florida when an aide whispered "America is under attack," a photo that captured the shock of 9/11.
Emotional response: He later visited Ground Zero, used a bullhorn to praise rescue crews and vowed the perpetrators would be held to account.
25 years on: Bush will attend the anniversary and display 16 paintings he made about the day — and a Reuters reporter still keeps his ash-covered shoes from Ground Zero as a memento.
