Why Did Joy Behar Leave 'The View' During Commercial Break?

Now you see her, now you don't! Joy Behar appeared on "The View" today, until the show went to commercial. When the show returned, the outspoken host was nowhere to be seen. ABC is not responding to speculation she left the set because she didn't want to share the stage with country star and "American Idol" judge Carrie Underwood. Behar has criticized Underwood's decision to perform at Donald Trump's inauguration last year.
