Storm Sandy: Obama surveys devastation in Atlantic City
US President Barack Obama has toured the state of New Jersey, to survey the devastation two days after the huge storm, Sandy, made landfall nearby.
With Republican Governor Chris Christie, he met rescue workers and residents in Atlantic City.
The massive cyclone killed 63 people across the north-eastern US, severing power to millions.
The disaster prompted Mr Obama to hold off campaigning for a third day ahead of next Tuesday's US elections.
He and Gov Christie boarded the presidential Marine One helicopter upon arrival in southern New Jersey on Wednesday for an aerial tour of the damage.
'Concern and compassion'
They were joined by the head of the Federal Emergency Management Agency, Craig Fugate.
At a joint news conference afterwards, Mr Obama said: "We are here for you and we will not forget. We will follow up to make sure you get all the help you need until you rebuild."
The president said he had set down a "15-minute rule" with his team for response to governors and mayors seeking federal assistance.
"We are not going to tolerate red tape; we're not going to tolerate bureaucracy," said Mr Obama, whom Republicans often accuse of over-regulation.
The New Jersey governor, usually one of Mr Obama's fiercest critics, spoke of his "great working relationship" with the Democratic president.
"I cannot thank the president enough for his personal concern and compassion for the people of our state," said the Republican.
Mr Obama praised the governor's "extraordinary leadership" and said Mr Christie had put his "heart and soul" into the relief effort.
Gov Christie has in recent days applauded Mr Obama's handling of the storm's aftermath.
BBC North America editor Mark Mardell, in Atlantic City, says such plaudits ring louder than anything a celebrity or supporter could say, and underline the power of incumbency.
Republican presidential nominee Mitt Romney cancelled campaign events at the height of the disaster, but is now back on the trail with rallies in the crucial swing state of Florida.
Mr Obama plans to resume campaigning on Thursday with stops in Nevada, Colorado and Wisconsin.
