There is still some debate as to whether a formal Impeachment Inquiry will help to expedite the documents and testimony that the House has been seeking for months.
The overwhelming consensus is that it won't hurt the investigation of sought documents and testimony.
That Trump has admitted to pressuring the Ukrainian President to find some dirt on Hunter Biden even though the Ukrainians have already investigated the matter and found nothing, the fact that Trump was holding up military aid until they came up with something is criminal.
Congress has every Right to see the whistleblowers report. A transcript of one phone conversation is not what they are seeking.
This is not about losing the election in 2016. It is about a sitting President on a least 10 occasions Obstruction justice as well as seeking foreign aid against his potential political opponent!
A third framing, which we address here, is a more practical one: whether, for the purposes of carrying out further investigation, the House’s hand would be strengthened significantly if it initiated impeachment proceedings. A May 15 letter from White House Counsel Pat Cipollone to Jerrold Nadler, chairman of the House Committee on the Judiciary, brings this question into stark relief. The 12-page letter states, in essence, that the White House will not be providing any documents or information requested by the committee as part of an investigation announced on March 4 “into the alleged obstruction of justice, public corruption, and other abuses of power by President Trump, his associates, and members of his Administration.” In its response, the White House outlines a host of political and legal arguments, relying heavily on the premise that Congress has no “legitimate legislative purpose” for requesting the materials. This sweeping repudiation of Congress’s oversight powers brings into stark relief the question of whether there are procedural advantages in pursuing the same information and lines of inquiry under the banner of impeachment proceedings.
Senate Republicans will have to decide if they support our Constitution or an Imperial Presidency.
