Dr. Ben Carson's publisher will be revising future editions of his book "America the Beautiful" in response to allegations that the conservative activist failed to properly credit source material.
"I attempted to appropriately cite and acknowledge all sources in `America the Beautiful,' but inadvertently missed some," Carson said in a statement issued Thursday through his literary agent, Sealy Yates. "I apologize, and I am working with my editors to rectify the situation."
A BuzzFeed story earlier this week noted close similarities between passages in Carson's 2012 book and material that first appeared elsewhere. "America the Beautiful" was co-written by Carson's wife, Candy Carson.
A spokeswoman for the publisher, Zondervan, issued a statement Thursday saying that "it has become apparent" that additional citations are needed.
"Any necessary updates will be made in subsequent printings," reads the statement from Zondervan, a Christian publisher owned by HarperCollins
Yates told The Associated Press on Wednesday that Carson had submitted all his sources to Zondervan before publication and thought that Zondervan would ensure there was attribution.
Carson, a former neurosurgeon, has been rumored as a possible Republican contender for the 2016 presidential election.
