Supreme Court ruling pulls rug out from under article of impeachment
The Hill, Jan 17, 2019

The decision by the Supreme Court to review the lower court rulings involving congressional and prosecution subpoenas directed toward President Trump undercuts the second article of impeachment that passed the House Judiciary Committee along party lines last week.

That second article of impeachment charges President Trump with obstruction of Congress for refusing to comply with the congressional subpoenas in the absence of a final court order. In so charging him, the House Judiciary Committee has arrogated to itself the power to decide the validity of subpoenas, and the power to determine whether claims of executive privilege must be recognized, both authorities that properly belong with the judicial branch of our government, not the legislative branch. The House of Representatives will do likewise, when it votes to approve the articles, as the chamber is expected to do so Wednesday.

But they are close enough. Even if the high court were eventually to rule against the claims by President Trump, the fact that the justices decided to hear them, in effect, supports his constitutional contention that he had the right to challenge congressional subpoenas in court, or to demand that those issuing the subpoenas seek to enforce them through court.
