Former Vice President Joe Biden inexplicably leaned forward and chomped down on his wife's finger as she spoke during a campaign stop in Iowa on Saturday.

Jill Biden had been speaking to a crowd and using her hands to gesture, barely missing her husband's face at several points.

Eventually, while her arm was outstretched, Biden leaned forward and bit down on the tip of his wife's index finger.

In response, Jill Biden laughed it off.

The pair were in Council Bluffs speaking to a crowd of several hundred people, according to the Associated Press. The Biden are launching an eight-day bus tour of Iowa ahead of the February 3 caucuses.

The latest Iowa polls show Biden competing nearly neck and neck with Sens. Elizabeth Warren and Bernie Sanders, and being edged out by South Bend Mayor Pete Buttigieg.
