Trump Says Russian Drone Breach May Have Been a ‘Mistake’

President Donald Trump said incursions by Russian drones into Polish airspace could have been a “mistake,” but also expressed his frustration with an incident that has alarmed Warsaw and other NATO allies.

“It could have been a mistake, but regardless, I’m not happy about anything having to do with that whole situation,” Trump told reporters Thursday at the White House as he left for a trip to New York. “But hopefully it’s going to come to an end.”
