The Daily Show host Jon Stewart will appear on Fox News’ The O’Reilly Factor on Monday to debate about rapper Common’s invitation to perform at a White House event. O’Reilly issued the challenge Thursday on his show. The two hosts have differing opinions on the rapper, who performed at a poetry event this week at the White House. Reilly questioned Common’s invitation, saying the rapper has defended cop killers in his songs. Stewart countered, more against O’Reilly’s views than about Common, triggering O’Reilly’s challenge.
