Hillary Clinton was wearing a mysterious box with wires during TV debate with Trump, conspiracy theorists claim in latest bizarre theory
Eagle-eyed viewers also noticed a clear earpiece attached to the Democrat candidate's ear on Monday night
BAFFLED TV viewers have struggled to explain a mysterious object hidden under Hillary Clinton's jacket during Monday's presidential debate.
The Democrat candidate appeared to have a box attached to her back with a wire running upwards.
And eagle-eyed viewers also noticed a see-through ear piece planted in Clinton's ear during her verbal sparring match with Republican Donald Trump.
Conspiracy theorists quickly raced to explain what the mysterious object was.
It was soon pointed out that rival Trump was not sporting a similarly-sized box.
In one bizarre theory, it was suggested the device was used to allay symptoms of Parkinson's disease.
