Chris Cuomo was on CNN calling his Mom on speaker phone in an attempt to prove Donald Trump wrong. Wrong about what? Possibly in response to Trump's tweet that said, "I have been watching people making phone calls my entire life. My hearing is, and has been, great. Never have I been watching a person making a call, which was not on speakerphone, and been able to hear or understand a conversation. I’ve even tried, but to no avail. Try it live!"
Cuomo tried it live and it didn't work very well! Ha!
