'Broad City' Actor Abbi Jacobson on New Book, Hillary Clinton Cameo

— -- Abbi Jacobson is gearing up for the fourth season of "Broad City."

The Comedy Central series has hosted many guest stars, including the Democratic presidential nominee Hillary Clinton.

"We've had such amazing actors but just to have Hillary was another level," Jacobson said today on "GMA."

"We had been trying to get in touch with someone in her campaign. We wrote it way before we shot it and I guess we did get a call," she explained. "It was unbelievable."

Clinton, along with other celebrities, is featured in Jacobson's new book of illustrations "Carry This Book," which is out today.

"Basically every spread is a different famous person or famous fictional character's contents of their bag...it's sort of my own little fan fiction of what they might carry with them," Jacobson said.

"I went to art school and so, my character Abbi is an illustrator as well and everything that she does on the show is stuff I've actually done," she added. "For the past six months I've been working on this and it's been so fun."
