"None of these tests indicated that I had cancer," Ms. Dunham wrote to Cigna, according to the book. After several months, Cigna denied the claim. Scott, who calls Obama's version of what happened "abbreviated" in her book, told the paper that she found no evidence that Dunham encountered similar challenges from Dunham's actual health insurance provider. Nicholas Papas, a White House spokesman, did not challenge Scott's account, which was based on actual letters Dunham had written to CIGNA, according to the Times . "We have not reviewed the letters or other material on which the author bases her account," he told the paper. "The president has told this story based on his recollection of events that took place more than 15 years ago."
