Not according to Nancy Pelosi. Whether or not she was telling the truth is another matter.

Uhhhhh, Pelosi reinforces the validity of the current subpoenas in her statement. Maybe try reading a primary source for once in your life? https://www.speaker.gov/newsroom/102819-0

For weeks, the President, his Counsel in the White House, and his allies in Congress have made the baseless claim that the House of Representatives’ impeachment inquiry “lacks the necessary authorization for a valid impeachment proceeding.”  They argue that, because the House has not taken a vote, they may simply pretend the impeachment inquiry does not exist.

Of course, this argument has no merit.  The Constitution provides that the House of Representatives “shall have the sole Power of Impeachment.”  Multiple past impeachments have gone forward without any authorizing resolutions.  Just last week, a federal court confirmed that the House is not required to hold a vote and that imposing such a requirement would be “an impermissible intrusion on the House’s constitutional authority.”  More than 300 legal scholars have also refuted this argument, concluding that “the Constitution does not mandate the process for impeachment and there is no constitutional requirement that the House of Representatives authorize an impeachment inquiry before one begins.”

The Trump Administration has made up this argument – apparently out of whole cloth – in order to justify its unprecedented cover-up, withhold key documents from multiple federal agencies, prevent critical witnesses from cooperating, and defy duly authorized subpoenas.

This week, we will bring a resolution to the Floor that affirms the ongoing, existing investigation that is currently being conducted by our committees as part of this impeachment inquiry, including all requests for documents, subpoenas for records and testimony, and any other investigative steps previously taken or to be taken as part of this investigation.  

You think District Court's don't make 95% of judge-made law in this Country? You're out of your mind. And one of them was the DC Circuit, so Congress is currently batting a thousand.

I challenge you to find the "editorializing" in the comment you just replied to.

Did you even read your own comment?

"This is not articles of impeachment, but rather it is designed to give Democrats better legal footing for their court cases."

Non lawyers are welcome. But don't be surprised when you get called out for being constantly wrong if you don't want to escape your right wing media bubble to read any semblance of primary source, or do research using actual cases or statutes.
