Trump responds after Iran denies his claim of talks, says they are 'duplicitous'

US President Donald Trump responded after Iran denied his claim that the Islamic nation is in talks with the US. "Iranian Leadership is unbelievably duplicitous! They ask for a meeting...and they say, openly...that they're not having any discussions," he wrote. "Whether Iran wants to admit it or not, we are...talking of a solution to a problem that they...caused," he added.
