Chair thrown during teacher-student fight in Florida

A Florida mother is livid and looking for answers after a fight broke out between her son and a teacher.

The video shows a chair flying in the air.

Isaiah Speights, 18, ended up on the ground.

Speights says it started when he made a smart remark to the high school teacher.

The teacher says Isaiah put his hands on him first.

Officials at the Treasure Coast School are investigating.
