(CNN) - Rudy Giuliani, a former New York City mayor, accused President Barack Obama in a Friday appearance on CNN's "Piers Morgan Tonight" of putting his own campaign ahead of handling the fallout from Superstorm Sandy.
"If I were the president of the United States, I sure wouldn't be flitting around the Midwest and the West," Giuliani said. "My job would be making sure this thing was followed through to the very end. Maybe the first couple of days he was keeping his eye on the ball, but we got gas lines now that are a mile long. We got bodies still being discovered, and we got a president who is playing campaigner in chief."

His comments on CNN came the same evening that Giuliani rallied thousands at an Ohio rally for GOP presidential nominee Mitt Romney, where he called for the president's resignation on the grounds of mishandling the economy. He blasted Obama as the "worst president for our economy in our lifetime" and said that if Obama "was paying attention, we wouldn't be going through all this investigation of what's being covered up about Libya."
"What the heck is he doing, flying all over the country and not keeping his attention on what's going on there, making sure people don't have to wait until November 11th or November 12th for the power to go back on?" he asked on CNN. "I understand he's still running for re-election, but his first responsibility is as commander-in-chief, and I think he's taken his eye off the ball at least for the last couple days. Maybe the first couple days he kept concentration on it. But I feel pretty darned offended seeing my president floating around campaigning while people are suffering the way people in New York, New Jersey and elsewhere are suffering."
White House officials have said Obama remains very much up to speed on the response to Sandy. The number of deaths in the United States blamed on the storm rose to 106 on Friday, and damage has been estimated at between $30 billion and $50 billion.
Obama visited the headquarters of the Federal Emergency Management Agency on Saturday morning before his day of campaign events, and White House officials have said that while on the campaign trail, he continues to be briefed on the response. As the storm approached and hit, Obama canceled several days of events and only returned to campaigning on Saturday.
"I can assure you, everybody on this team, everybody sitting around the table, has made this a No. 1 priority, and this continues to be my No. 1 priority," Obama told reporters after the meeting. "There is nothing more important than us getting this right, and we're going to spend as much time, effort and energy as is necessary to make sure that all the people in New York, New Jersey and Connecticut know that the entire country is behind them in this difficult recovery effort."
Obama convened meetings in the White House Situation Room on Monday and Tuesday, a senior administration official said, as the storm ravaged the Mid-Atlantic and then Northeastern United States.
"The president is focused on the response to Sandy, on making sure the federal government is doing everything within its means to assist state and local officials and the millions of people affected by the storm. He's very intense about it," a White House official said Tuesday.
Obama canceled campaign events on Wednesday and instead traveled to New Jersey and surveyed the damage with Gov. Chris Christie. After the tour, Obama thanked first responders for their efforts, expressed his sympathy for those who lost homes and loved ones and said the federal government would continue to participate in the response efforts.
"What I can promise you is that the federal government will be working as closely as possible with the state and local officials, and we will not quit until this is done," Obama said. "We are not going to tolerate red tape. We're not going to tolerate bureaucracy. And I've instituted a 15-minute rule, essentially, on my team: You return everybody's phone calls in 15 minutes, whether it's the mayors, the governors, county officials. If they need something, we figure out a way to say yes."
The president held "conference calls throughout the day with local elected officials from impacted areas to ensure that available federal resources are being provided in support of local response efforts," on Thursday, a White House official said. Obama also held campaign events on Thursday and Friday.
On Friday, Secretary of Homeland Security Janet Napolitano visited New York, including the hard-hit Staten Island, and issued a waiver to expedite the delivery of fuel by ship to Northeastern ports. The Department of Defense also announced it would deliver an additional 24 million gallons of fuel to the region.
Pressed by CNN's Piers Morgan, Giuliani maintained Obama's efforts were not enough.
"It's a heavy charge to level at him, Rudy," Morgan said. "Wouldn't people just say straight away well, if Mitt Romney is campaigning over the last 48 hours, then surely the president who only has four days left until the general election has to campaign, too? Doesn't he?"
"Sure he can, but he could divide his time, couldn't he?" Giuliani replied. "I don't see how he's spending any time focused on this."
