My goodness, you apparent ignorance of the facts is exhausting, CBB.
Trump is being impeached for two articles. Abuse of Power, and Obstruction of Congress. The Democrats meticulously laid out both articles ad nauseum these past 3 days. And a review of the Federalist Papers and other documents at the time make it clear that laws need not be broken by the President in order to be impeached. In large part because the President has powers with potential abuse that no other citizens possess, and therefore Congress is not in the habit of passing laws that try to foresee every conceivable abuse of power that a President might someday commit. But attempting to bribe the Ukrainian president by withholding military aid to an ally during a time of wartime crisis, solely for his own personal benefit (insisting that Zelinsky dig up dirt on Biden's son) constitutes an obvious abuse of power. And they could have included a charge of bribery as well.
Additionally, on January 16, 2020, the Government Accountability Office, a nonpartisan watchdog agency, stated that Trump broke the law by withholding military aid to Ukraine that had been legislated by Congress. This was a violation of the Impoundment Control Act of 1974.
Lastly, the Constitution grants Congress the right to impeachment of the President. By refusing to hand over documents and witnesses that would be helpful in conducting the impeachment process, Trump has obviously obstructed Congress from fulfilling its Constitutional duties. President Clinton fulfilled his oath to defend and protect the Constitution; President Trump has elected to thumb his nose at the Constitution.
Despite the fact that a supplicant Republican Senate majority is unlikely to convict Trump, the members of the House felt they had a duty to defend the Constitution, and even Pelosi acquiesced to proceeding once the evidence of his attempted bribery became overwhelming. The facts are not in dispute. The only defense his Senate allies have is that his crimes and abuse do not rise to the level of severity necessary to impeach, a conveniently subjective assessment.
