how does he circumvent the mute button?
Bring in a bull-horn
Maybe they want a mute button so they can block Trump’s voice in his ear so Biden can’t hear him at all and be distracted. Muting Biden’s HEARING between questions?
“how does he circumvent the mute button?”
Completely ignores the questions of the moderator. Says what he wants to say about any subject he wants to, and asks Biden questions about Hunter for 2 minutes and then stops talking.
Rinse. Repeat for the entire “debate”.
