Tony Bobulinski, a former business associate of the Biden family, got into a fiery exchange with Rep. Alexandria Ocasio-Cortez (D-NY) during an impeachment hearing on Wednesday.

Ocasio-Cortez — known as “AOC” for short — began her five minutes of speaking to the witnesses by asking Bobulinski a “simple” question: Was it his testimony that he personally witnessed President Joe Biden commit a crime?

Bobulinski said “yes,” after which the congresswoman pressed him to name the crime. “How much time do I have to go through it?” he quipped.

“It is simple, you name the crime,” Ocasio-Cortez shot back. “Did you watch him steal something?” she added.
