Rep. Adam Schiff recently revealed that, before he entered politics, he wanted to be a screenwriter. He even penned scripts for a courtroom drama and an action-filled spy thriller. Mr. Schiff, now leading the Democratic push to impeach President Trump, hasn’t lost his theatrical flair.

He insisted for months that there was “ample evidence of collusion in plain sight” before the Mueller report blew that claim to hell. Then there was Mr. Schiff’s opening statement for the impeachment proceedings, in which he reimagined Mr. Trump’s call with Ukrainian President Volodymyr Zelensky, presenting an alternate script. It was largely panned as a B-movie “Godfather” rip-off.

Now the would-be dramatist is staging a new production: “Impeaching the President.” His script features secret sessions in the Capitol basement, anonymous whistleblowers, constant and selective leaks of testimony, and, of course, a brilliant performance by the heroic lead.

Count me as a skeptic, and not only because we know how this drama is likely to end: with an almost straight party-line vote by the House to impeach Mr. Trump and a near-straight party-line vote by the Senate not to remove him from office.

I’m also skeptical because I was cast in an earlier Schiff production, following my September 2007 departure as deputy White House chief of staff. On May 22, 2008, the House Judiciary Committee subpoenaed me to answer questions regarding the Bush administration’s removal of nine U.S. attorneys starting in 2006 and the prosecution of Don Siegelman, a former Democratic governor of Alabama, who was convicted in 2006 of bribery and fraud and sentenced to seven years.
