Question 1: What did the president want from Ukraine?
The Democrats presented testimony that Trump cared much more about getting Ukraine to investigate the Biden family than he did about advancing American national security. That’s the most likely explanation for the five-week hold on aid to Ukraine. But the Republicans have offered a plausible alternative, though not an entirely convincing one. Given Ukraine’s dismal record on corruption, they say, wasn’t it prudent to wait briefly and see whether country’s new president lived up to his big promises?
Question 2: Can the Democrats prove their case?
Can they show conclusively that the president wanted something illicit and was using official resources to get it?
Democrats need firsthand proof of Trump’s motives to demolish the Republican case. That means they need documents or testimony from people who dealt directly with the president. Democrats have subpoenaed some of Trump’s close aides; the president ordered them not to testify. Nancy Pelosi has decided to skip over them rather than wait for the Federal Courts to adjudicate the conflict between the two branches.
The result, so far, is what Scottish courts call “unproven.” Crimes that carry draconian punishment rightly require conclusive evidence to match. The Democrats simply cannot produce it without firsthand accounts.
Question 3: What’s the rush?
The Democrats argue — and have presented testimony — that Trump cared a lot more about getting Ukraine to investigate the Biden family than he did about advancing American national security. If Trump’s real goal was bringing down the Bidens, and if he tried to get Kyiv to do that by leveraging U.S. foreign aid and the prospect of a White House meeting, then he would be wrongly seeking personal, political benefits from a foreign government against a likely 2020 competitor.
Those are reasonable arguments. Indeed, they are the most likely explanations for the 55-day hold on aid to Ukraine, which Congress had authorized. Still, other explanations are possible, and the White House and its Republican allies have offered them. They say Trump had perfectly legitimate national-security concerns about U.S. policy in Ukraine, that he had often mentioned them to advisers, and that he paused the aid as he evaluated them.
