You may recall that the House Republicans held up aid to Ukraine, Taiwan and Israel (and blew off a very expansive border bill on Trump’s orders) for months. These Republicans attempting to impeach Biden over this issue is mind-boggling.
I’ve heard several wingnut commentators compare Biden’s actions to Trump’s when he told Zelensky that he would withhold weapons unless he came up with dirt on Joe Biden. I don’t think I need to point out how ridiculous that comparison is. If they disagree with Biden’s decision that’s completely legitimate. They can try to write some legislation to stop him or someone on their team could file a lawsuit. But there are decades of precedents that say presidents have the authority to make a decision like this on the basis of the national interest (often at the behest of Republican hawks who argue for unlimited presidential power.) Trump, on the other hand, used his authority to advance his personal political interest. You’ll recall that Alan Dershowitz fatuously tried to argue that a president’s personal political interest is by definition in the national interest — another example of l’etat c’est moi.
Presidents have often made dubious decisions in this area and there are good reasons to dial back their unrestrained authority. But impeaching Biden over this is absurd and they know it.
