US National Security adviser John Bolton is a ''pathological liar'', Cuban Foreign Minister Bruno Rodriguez has asserted in Twitter.
The head of Diplomacy rebuffed Bolton's allegations in which the US official call Cuban doctors working in Venezuela 'repressors'.
He further wrote that Bolton missed to say that 400,000 Cuban health professionals have worked in 134 countries, and that Cuban ophthalmologists have made 3.4 million free eye surgeries.
Bolton is one of Washington's hawks in the Trump administration who together with Senator Marcos Rubio have advised the President to harden the economic, financial and commercial blockade on the neighboring island.
To justify their actions they have, for instance, included Cuba in the White House black lists as it recently did by mentioning the island among nations that encourage human trafficking, just like they have done with Venezuela and Nicaragua.
