A Russian spy plane 'trolled' Donald Trump with a reconnaissance flight over Washington DC and New Jersey.
Officials at the Pentagon confirmed to Politico that the plane had flown above the US capital and the eastern state on Wednesday (August 9).
The Treaty on Open Skies - which came into effect in 1992 - ensured this action was perfectly legal, as it allows Russia and the United States to implement surveillance flights over the other's territories.
But some would argue the plane's crew were guilty of excessive provocation, as they flew directly over the DC area and Bedminster in New Jersey, where the US President had been temporarily staying.
The same official who confirmed the flight said such a mission was fairly routine.
The individual explained to Politico that the Russians had given them the required 72 hours' notice before undertaking the flight, and American personnel had been on board to observe it.
The Treaty on Open Skies aims to promote military openness among the signatory countries, which include Russia, the US, and Canada, among others.
