President Joe Biden ignited a firestorm on social media Thursday after he appeared to nibble on the shoulder of a little girl in Helinski, Finland.

In the video, Biden can be seen stooping over a little child whose mother is holding her. Biden seemed to constantly nip at the girl’s shoulder with his tongue. The girl can be seen backing away while appearing alarmed by his behavior.

The mother appeared to laugh at the incident and then tried to take a selfie with the president. As she did, Biden started to approach the little girl a second time with his mouth and she turned her head away.

The incident happened when Biden greeted families at Helsinki-Vantaan International Airport before boarding Air Force One.
