Does the DOJ's opinion, binding or not, actually matter with respect to this though? Impeachment is solely the prerogative of the House, and more broadly Congress. I don't see how the DOJ as part of the executive branch can thus bind the House at all in this.
(Also worth noting that Impeachment technically isn't a legal matter -- it is a political process.)
But typically, Justice Department internal opinions — though they have no binding legal weight in court — are controlling on subsequent administrations unless they’re revoked or superseded by new opinions.
If the House continues with an inquiry, and subpoenas people and records, the White House response will be that their inquiry per legal opinion is invalid and also to pound sand.
Trump wanted to force Pelosi to take a vote and had the DOJ write this opinion. You know what Pelosi did? She took a vote.
It's just a majority vote and the GOPs outnumber House Democrats by 10 members. So, a very real chance that this impeachment will happen. Dems in the Senate have 2 members who are very GOP-friendly. Manchin and Sinema. So there is a small chance here for Biden to actually be removed from office.
Oh, that's right! Sorry forgot about that. Well, that's at least good. Even if they don't get a removal though, it still normalizes impeachment which is the GOP plan.
This is about starting an inquiry. The Republicans don't have the votes to start. Plenty of Republicans will not vote for an inquiry. McCarthy tried starting without a vote today.
