EXCLUSIVE: Christine O'Donnell On Gay Marriage, Piers Morgan And Her Memoir's Fiction Disclaimer (VIDEO)

WASHINGTON -- Former Delaware Senate candidate Christine O'Donnell attempted to salvage her national book tour Thursday night at a downtown Barnes & Noble, where she signed copies of the newly released "Troublemaker" for about a dozen fans.

The event capped off a rocky two days marked by O'Donnell's refusal to answer pointed questions about her political record. On Wednesday, she abruptly walked out during a live interview with CNN's Piers Morgan when he questioned her views on gay marriage. On Thursday morning, she hung up the phone during a radio interview when the conversation grew testy.

O'Donnell describes "Troublemaker" as "a political memoir slash campaign diary slash position paper slash rallying cry" in the book's introduction. After she signed books, she did an interview with The Huffington Post.
