WATCH: Hunter Biden rips Donald Trump Jr. in 'Jimmy Kimmel Live!' interview

Out promoting his new book, “Beautiful Things,” Hunter Biden was a recent guest on “Jimmy Kimmel Live!.” In addition to discussing his drug addiction, he talked Burisma, Rudy Giuliani, and ongoing attacks from Donald Trump Jr.

Biden brushed off Trump Jr. in a matter of nano-seconds calling his insults “wildly comical.” Adding, “That is putting it lightly,” President Biden’s son said.

Kimmel then asked Biden if he knew or had ever met the eldest son of ex-President Donald Trump,

“I am absolutely within my rights to question anything that comes from the desk fo Rudy Guiliani," he said.
