Top American scientist, Bennet Omalu, has made a ludicrous suggestion on Twitter that Donald Trump and Vladimir Putin are poisoning presidential candidate Hillary Clinton and this is the reason for her spathe of health problems.

‘I must advise the Clinton campaign to perform toxicologic analysis of Ms Clinton’s blood,’ he wrote. ‘It is possible she is being poisoned.’

Then, in a second tweet, he went onto suggest that Putin and Trump were responsible: ‘I do not trust Mr Putin and Mr Trump. With those two all things are possible.’
