Chicago Mayor Rahm Emanuel (D) on Sunday advised presumptive Republican nominee Mitt Romney to “stop whining” about suggestions that he broke the law or lied to voters by saying he had “retired” from Bain Capital, even though Security and Exchange Commission (SEC) documents show that he was in charge of the company.

After The Boston Globe revealed on Thursday that Romney was listed as the “sole stockholder, chairman of the board, chief executive officer, and president” of Bain even after he claimed he had retired in 1999, Obama deputy campaign manager Stephanie Cutter noted that lying on SEC filings was a felony.

On Friday, Romney scheduled last-minute interviews on five television networks to demand an apology from President Barack Obama.

“He sure as heck ought to say that he’s sorry for the kinds of attacks that are coming from his team,” the former Massachusetts governor complained to ABC News. “If I were president of the United States, I would put a stop to it and apologize to my campaign for what has been done by his.”

“What kind of a president would have a campaign that says something like that about the nominee of another party?” Romney asked during an interview with CBS News.

During an interview with ABC News’ George Stephanopoulos on Sunday, Emanuel pointed out that Romney’s protests made him look less than presidential.
