"Why is the Trump Administration so hell-bent on keeping this secret? Because on the call in question, Trump may have made a request for Ukraine to interfere in the 2020 election in exchange for improved relations with the US. It has yet to be confirmed that the quid pro quo was the nature of the call, but if it was, it would be more damning than anything in the Mueller report. This would be using the power of the presidency to extort an ally in exchange for election assistance. This call would be corrupt on its own, but this is exactly what it sounds like. The President of the United States, his personal attorney, and the United States Government have been actively and publicly pressuring a foreign power to dig up dirt on a political opponent and interfere in American democracy."
