We urge our readers to tune into their TVs, radios, tablets and/or mobile devices at 10 a.m. Thursday, June 8, to hear former FBI Director James Comey testify before the Senate Intelligence Committee about President Trump’s conduct in connection with the investigation into Russian influence in the 2016 election, as well as his ties to Russia and those of his campaign aides and administration officials.

The president reportedly tried to dissuade or halt Mr. Comey’s probe before suddenly booting him out of the FBI in early May.

Just what is President Trump trying to hide?

We believe the Senate committee, under the steady and balanced leadership of Democratic Sen. Mark R. Warner of Virginia and GOP Sen. Richard M. Burr of North Carolina, will uncover the facts. Nothing has been as serious, significant or urgent to our democracy since the Watergate scandal in the 1970s.

When Mr. Comey takes the stand and testifies, we hope he will do as the old folks used to say: Tell the truth and shame the devil.

Yes, President Trump has a lot to be ashamed of — and so do the people who voted him into office.

As a result of these hearings, the American people may well see with President Trump a replay of the impeachment process that led to the resignation of President Richard Nixon in August 1974.

Obstruction of justice, abuse of power and contempt of Congress were the charges against President Nixon at the time. With the coming day’s testimony, the same charges may prove to be President Trump’s end.
