This has been the plan from the start, they opened the “investigation” without a vote so per Trump admin precedent the Biden admin has not considered it legitimate.

Then you wait a bit and the moderates get to say “we TRIED every other way but the administration forced our hand!” And they all vote for the official inquiry.

I’d still be surprised if they got the near-unanimity needed (especially if they expell Santos on Thurs), if they get it then I’d bet impeachment inquiries just become something that the House does whenever they are controlled by the party opposed to the President.
