WASHINGTON - President Donald Trump says Harvey "has profoundly affected our entire nation" and he's praising what he calls "heroic efforts" in the wake of the devastating storm.

  

Trump is carrying a message to victims as he prepares for his trip Saturday to Houston and Lake Charles, Louisiana.

  

As he says in his weekly radio address: "We are with you every single step of the way. We will help you recover. We will help you rebuild.  We will support you today, tomorrow, and the day after."

  

Trump was in Texas earlier in the week, too, and he says he saw "a spirit of love, determination and resolve. A spirit, that even when wounded, never gives up, never gives in, never loses hope."

  

The president says storm victims face " a long and difficult path" ahead, but he says that "we are stronger than the obstacles in our path."
