(CNN)Talk about candid camera.
Former Vice President Joe Biden was spotted Thursday chatting it up with a homeless man outside of a movie theater in Washington, D.C., according to a tipster who alerted Politico of the interaction.
The tipster sent Politico a candid photo of Biden, who appears to be in conversation with a man the tipster said was homeless. The photo, which was also posted on Facebook, has received nearly 40,000 shares and more than 50,000 likes.
According to Politico, the former vice president was leaving the theater in Georgetown with his granddaughter, who was in town visiting friends, when the conversation occurred. Biden's spokesman declined to comment on the interaction.
Earlier this week, Biden was in Pennsylvania campaigning for Democrat Conor Lamb, who will be on the ballot in the House special election there on Tuesday. Lamb will face off against Republican state Rep. Rick Saccone, who is backed by President Donald Trump.
Showing mutual affection, Biden told a crowd of supporters that Lamb "reminds me of my son Beau," and Lamb twice introduced Biden as "a leader everybody likes."
