If only Barack Obama was more like Ronald Reagan.

That was the advice once again offered by former Mayor Rudy Giuliani yesterday, who reemphasized that he does not believe "the president loves America" and said the country's next leader should be more like President Reagan, in an appearance on John Catsimatidis' show on AM970 The Answer.

"We need an American president more like Ronald Reagan, who gives us a sense of optimism and sees American exceptionalism and doesn't see us as just another country," said Giuliani, himself a one-time presidential contender.

Giuliani was explaining remarks about Obama he made Wednesday at a New York City dinner for 2016 hopeful Gov. Scott Walker of Wisconsin. At the dinner, he said that Obama "wasn't brought up the way you were brought up and I was brought up through love of this country."

"I've said it, maybe, 30 times before. But somehow, this time, it hit a nerve," Giuliani said on the radio. "Maybe because the president is on such defense about his unwillingness to say 'Islamic extremist terrorism.'"

The former mayor also told CNN that his secretary had received death threats and that he does not regret his remarks.

Homeland Security chief Jeh Johnson found the remarks regrettable, he said on CNN. "I'm sorry to see statements like that coming from the former mayor, whose response to 9/11 in 2001 I admired very much."
