The individual, who has not been publicly identified, was apparently concerned with a phone call Trump made with a foreign leader. It was said to include "a promise" that was so deeply disturbing to the individual that they lodged a formal complaint.

The Post also reported that Trump had interacted with several foreign leaders in the five weeks before the complaint was filed, including Russian President Vladimir Putin and North Korean leader Kim Jong-Un. But Trump initiated a call with Putin, the only one he's known to have spoken on the phone with.

The complaint is said to involve Trump and Ukraine, according to The New York Times. Back in July, Trump told the new Ukrainian president Volodymyr Zelensky that US-Ukraine ties could be improved if the country investigated corruption more forcefully.

And some of Trump's allies - like his personal lawyer Rudy Giuliani - have pushed the Ukrainian government to look into the dealings of Trump's political rivals, which include former Vice President Joe Biden.
