"Very interesting theory from our president that he has really good hearing, some would say, the best hearing ever, and he's never been able to hear a phone call when it wasn’t on speakerphone from anybody," the veteran newsman said during CNN's live coverage while the impeachment hearing was recessed before calling his mother.

"So, let’s just play with that for a second. Mom, can you hear me? All right.

"Can you just say hello? Mom? She probably can’t hear me," he added.

"Mom, can you hear me?" Cuomo asked again before putting the phone on speaker.

"Yes, I hear you. When you talk to me, I hear you," Cuomo's mother finally responded before Cuomo quickly pivoted away from the experiment.

“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!” Trump tweeted.

Holmes testified before the House Intelligence Committee on Thursday that Trump's voice was loud enough to overhear what he told Sondland in regards to Ukraine.

Cuomo's experiment also stirred blowback on social media.

I found it totally believable that Holmes could hear Trump’s conversation until Cuomo tried to prove it! Now I’m skeptical!
