Did Hillary Melt Down After Matt Lauer's Town Hall?

Bill Still has produced this video based on an email he received from someone within Castcom (NBC Universal's parent company). It claims that after the Matt Lauer-hosted townhall with Hillary Clinton and Donald Trump, Clinton had a massive meltdown once off-stage because she was expected a different question from Lauer than what he asked. Clinton also reportedly exploded at Donna Brazile, who is now at the center of  controversy surrounding reports she forwarded a debate question to Clinton that she had allegedly received from Roland Martin.

If Lauer thinks the public has a right to know the answers to his hard questions to Mrs Clinton, and if he has knowledge of this incident either directly or indirectly, don't the American people have a right to know from Lauer?
