One of Mitt Romney's biggest supporters, New Jersey Gov. Chris Christie, had nothing but praise for President Barack Obama today, as his state prepares to rebuild from the damage caused by Hurricane Sandy.

"I have to say, the administration, the president, himself and FEMA Administrator Craig Fugate have been outstanding with us so far," Christie said on Good Morning America. "We have a great partnership with them."

Christie told ABC's George Stephanopoulos that Obama called him on Monday night around midnight to ask if there was anything else the federal government could do to help. Christie added that they worked together to move forward with a Major Disaster Declaration for New Jersey.

The Major Disaster Declaration provides funding for recovery efforts, including infrastructure projects, temporary housing, low-cost loans to cover uninsured property loss and assistance to individuals and businesses.

"He worked on that last night with me…offered any other assets that we needed to help," Christie said. "I want to thank the president personally for his personal attention to this."

Appearing on Fox News, Christie said the storm is bigger than the election.

"I have a job in New Jersey that is much bigger than presidential politics," Gov. Chris Christie said on the show Fox & Friends. "I couldn't care less about that."
