You are not to be faulted if you think a formal inquest is under way and that legal process has been issued. The misimpression is completely understandable if you have been taking in media coverage — in particular, reporting on a haughty Sept. 27 letter from House Democrats, presuming to direct Secretary of State Mike Pompeo, on pain of citation for obstruction, to cooperate in their demands to depose State Department officials and review various records. 

The letter is signed by not one but three committee chairmen. Remember your elementary math, though: Zero is still zero even when multiplied by three.

What is portrayed as an "impeachment inquiry" is actually just a made-for-cable-TV political soap opera. The House of Representatives is not conducting a formal impeachment inquiry. To the contrary, congressional Democrats are conducting the 2020 political campaign. 

The House has not voted as a body to authorize an impeachment inquiry. What we have are partisan theatrics, proceeding under the ipse dixit of Speaker Nancy Pelosi (D-Calif.). It raises the profile, but not the legitimacy, of the same "impeachment inquiry" House Judiciary Committee Chairman Jerrold Nadler (D-N.Y.) previously tried to abracadabra into being without a committee vote.

Moreover, there are no subpoenas. As Secretary Pompeo observed in his fittingly tart response on Tuesday, what the committee chairmen issued was merely a letter. Its huffing and puffing notwithstanding, the letter is nothing more than an informal request for voluntary cooperation. Legally, it has no compulsive power. If anything, it is rife with legal deficiencies.

The Democrats, of course, hope you don't notice that the House is not conducting a formal impeachment inquiry. They are using the guise of frenetic activity by several standing committees — Intelligence, Judiciary, Foreign Affairs, Oversight and Reform, Financial Services, and Ways and Means — whose normal oversight functions are being gussied up to look like serious impeachment business.

But standing committees do have subpoena power, so why not use it? Well, because subpoenas get litigated in court when the people or agencies on the receiving end object. Democrats want to have an impeachment show — um, inquiry — on television; they do not want to defend its bona fides in court.
