If we had our druthers, we’d want the U. S. House Intelligence Committee to keep broadening its investigation. The world is simply learning so much about American and Ukrainian corruption, as well as the need for strong institutions and independent journalism. Hardly a day goes by without another breathtaking revelation.

We hope that prosecutors are taking note and pursuing leads. We hope that committee chairman Adam Schiff widens his probe of wrongdoing involving both nations. As Washington Post columnist Jackson Diehl noted this week, U.S. President Donald J. Trump’s attempted shakedown of Ukrainian President Volodymyr Zelensky — financial aid and a White House meeting in exchange for dirt on former Vice President Joseph Biden – looks more like a standard operating procedure than an aberration.
