Top Clinton aide denies report that he plans to vote for Romney

The National Memo also quoted Democratic National Committee executive director Patrick Gaspard, a former White House aide, saying that Band has been a strong supporter of Obama for some time now.

"There has never been any mystery about Doug Band’s support for President Obama over the past three-and-a-half years," The National Memo quoted Gaspard as saying. "He has helped us in every aspect of our work, from politics and policy to fundraising. Doug is our friend and there is no question about his unwavering support for Barack Obama."

In an article on about an improved relationship between Clinton and Obama, Band is reported to have said that "he will vote for Romney" in November. The magazine noted that Band refused to comment for the article. 

Clinton is set to deliver a speech at the Democratic National Convention in Charlotte, N.C., on Wednesday.
