Ukraine meddled in the 2016 presidential election. The Ukrainian government campaigned against Donald Trump in 2016. These are facts. Cold, hard math. When the swamp screams that something has been "debunked" or is "without evidence" you need to sit up, put down the coffee, and carefully investigate.
Impeaching President Donald Trump is legally invalid. The chief law enforcement officer of the United States of America requested that Ukraine assist our attorney general investigate suspected criminal activity in 2014 through 2016.
Yet Ukraine already entered into the "Treaty Between the United States of America and Ukraine on Mutual Legal Assistance in Criminal Matters," negotiated by President William Clinton, and ratified by the U.S. Senate in 2000.
