BYRON YORK: Why did Trump release Ukraine aid? The answer is simple.

Trump’s true reason for releasing the aid matters to the Democratic impeachment scheme. If he released the money after learning about the whistleblower — after he realized the jig was up — then that, at least to Democrats, suggests guilt. If he released it after gaining confidence in Zelensky, that does not suggest guilt.

But the evidence suggests that neither explanation is correct, that there is a much simpler reason for Trump’s decision to release the aid. On the day he OK’d the aid, Trump learned that Congress was going to force his hand and spend the money anyway. He could either go along or get run over. . . .

It was an entirely unremarkable end to the story: President tries to do something. Congress opposes. President sees he has no support and backs down. It has happened many, many times with many, many presidents.

In the end, the release of the aid is not dramatic proof of anything in the Trump-Ukraine matter. The facts do not support the Democratic notion that the president “got caught,” knew he was guilty, and gave in. It is not a smoking gun. It is a story of a president and Congress bumping up against each other on spending, and, as often happens, Congress won.

Well, where’s the drama in that?
