Clinton approached the squirrel, clad in a t-shirt reading "Another Clinton in the White House is Nuts," just before her CNN town hall event outside the Newseum in Washington, DC.
"Hello Mr. Squirrel, how are you?" Clinton said with a smile. "I know you've been following me around and while you're in between your gigs. I wanted you to get a copy of my book."
"I hope that you will make the hard choice and read my book," she added. "But you bring a smile to a lot of people's face."
The squirrel quietly accepted the peace offering from Clinton but was more vocal on Twitter.
"Thank you, @HillaryClinton! I love fiction!" the squirrel later tweeted.
