While what President Trump did in withholding military assistance from Ukraine to leverage President Zelensky to announce investigation of the Bidens may not rise to a cause for Trump's removal, I do not believe that his conduct should go uncensured. As Dershowitz, Mulvaney and others have said, quid pro quo exchanges have been a often used foreign policy tool, but only for persuading other nations to behave in ways that would the national interests of the United States. What Trump did was attempt Ukraine to behave in a way that would serve only his personal political interests. That, like so much of President Trump's behavior in office, is contemptible, and the Senate should have the political will to call out that behavior officially. Regarding the Obstruction of Congress article, I am in agreement with Trump's defense lawyers that the House failed to follow the well recognized course of seeking judicial orders to enforce their subpoenas. By failing to follow that course to uphold the constitutional authority of the Legislative Branch to oversee the actions of the Executive, the House failed to recognize the constitutional role of the Judicial Branch to adjudicate disputes between the Executive and the Legislative Branches. Even if -- and perhaps especially -- when the Executive's actions are corrupt, the Legislative Branch should seek the support of the Judicial Branch when contemplating impeachment of the president.
