Upbeat Trump pitches in at shelter for Harvey victims

An upbeat and optimistic president visited with victims of Harvey on Saturday, touring a Houston mega-shelter housing hundreds of displaced people and briefly walking streets lined with soggy, discarded possessions. Trump met the scene with positivity, congratulating officials on an emergency response still in progress and telling reporters that he'd seen "a lot of love" and "a lot of happiness" in the devastation the storm left behind. "As tough as this was, it's been a wonderful thing," Trump said of the Harvey response after spending time with displaced children inside NRG Center, an emergency refuge housing about 1,800 evacuees.
