"Joe Biden's handlers several days ago agreed to a pre-debate inspection for electronic earpieces but today abruptly reversed themselves and declined. Biden's handlers have asked for multiple breaks during the debate, which President Trump doesn't need, so we have rejected that request. On top of the refusal to take a drug test, it seems pretty obvious that the Biden team is looking for any safety net they can find in the hours leading up to the debate. With his 47 years as a failed Washington politician, how much help does Biden want?"
