Washington (CNN) -- Senate Majority Leader Harry Reid apologized Saturday for making racially insensitive remarks about Barack Obama during the presidential campaign.
Journalists Mark Halperin and John Heilemann reported the remarks in their new book "Game Change," which is scheduled to be in bookstores Tuesday.

The authors quote Reid as saying privately that Obama, as a black candidate, could be successful thanks, in part, to his "light-skinned" appearance and speaking patterns "with no Negro dialect, unless he wanted to have one."

"He [Reid] was wowed by Obama's oratorical gifts and believed that the country was ready to embrace a black presidential candidate, especially one such as Obama -- a 'light-skinned' African American 'with no Negro dialect, unless he wanted to have one,' " Halperin and Heilemann say.

"Reid was convinced, in fact, that Obama's race would help him more than hurt him in a bid for the Democratic nomination," they write.
