On Friday, November 2, Trump posted from his official Twitter account, a message for his followers which go beyond 55 million.
The message read 'Sanctions are Coming, November 5' and referred to the famous GoT line 'Winter is Coming'. The image incorporated the show's title font.
Trump's message was a warning to Iran about reimposing US sanctions which were lifted under 2015's nuclear deal.
Do you know?
The long night comes with it
The quote 'Winter is Coming' is often repeated by the Starks on the show and it refers to the battle between the living and the dead that will be fought in the show's final season which releases in the first half of 2019.
A little about the US sanctions
For those unaware, Trump's administration informed that the sanctions imposed on Iran's banking and shipping sectors, shipbuilding, and energy would go into effect on Monday, November 5.
This move follows Trump's withdrawal from US participation in the nuclear deal and serves to undo another of his predecessor, Barack Obama's, foreign policies.
Trump celebrated this news through his tweet, which HBO quickly reacted to.
HBO screams trademark misuse at Trump
HBO was quick to stand their ground and express their stance against Trump misusing the show lines to push a political decision.
They stated, "We were not aware of this messaging and would prefer our trademark not be misappropriated for political purposes".
They also jokingly tweeted from their official account asking how to say trademark misuse in Dothraki, the show's fictional language.
