Does this image prove Hillary Clinton was secretly wearing a wire during TV debate?

There has been no shortage of conspiracy theories about Presidential candidate Hillary Clinton this election - including allegations that she is a robot, or has been replaced by a doby double.

But the latest round may be a little more credible - after observers puzzled over what appears to be the outline of a battery pack and wires under her jacket during the Presidential debate.

Conspiracy theorists immediately seized on the box - in some images a wire is clearly visible - as evidence Hillary was ‘cheating’ by having answers fed to her by an outside team.

Others - more bizarrely - claimed that the machine might be to do with Clinton’s (alleged) ill-health, with some claiming that it was a ‘coughing prevention machine’.

But the reality may be a little more prosaic.

Hoax debunking site Snopes says that it’s almost certainly just the battery pack for the lapel microphone worn by Clinton.

Snopes says, ‘Even though the candidates both stood in front of mounted microphones on the debate stage, Hillary Clinton and Donald Trump also wore lapel mics:

‘A lapel mic is typically connected to a wire that is hidden underneath clothing and connected to a transmitter.

‘Clinton’s ears and neck were also clearly visible during the debate. While a “secret wire” could have been concealed in her dress, a wire connected to an earpiece mounted in or behind her ear would have been noticeable.’
