The “House Bolton Maneuver” was a pre-planned operation to use a timed NSC ‘resistance’ leak to frame a new demand for testimony in the Senate. From the beginning the House intentionally constructed an impeachment process to avoid the judicial branch because the construction of the articles was dependent on an unconstitutional creation: impeachment by decree of the Speaker.
As a result of their approach, the House fully intended to usurp their lack of judicial subpoena authority by placing political pressure on the Senate to call the trial witnesses they knew were unattainable due to separation of powers within the constitutional process. By design the House plan puts the burden of compulsory witness testimony upon the Senate because the House refused to create their own authority with a vote to initiate the impeachment process.
The House effort was, and is, an end-run around the constitutional outline for impeachment. This was not a flaw; it was a feature of the House creation.
