President Joe Biden has an easy way to completely derail the GOP impeachment inquiry if, as he insists, there’s really absolutely nothing there: Just hand over your bank records, sir, and those of Hunter and his shell companies.

Seeing those records is the central reason Speaker Kevin McCarthy upgraded House investigations to such an inquiry, now that they’ve established such hard facts as:

Once upon a time, our president insisted he “never spoke” to his son about his foreign business deals. Later, the claim became that he “was never in business” with Hunter, and/or that these meetings only involved discussing the weather.

More recently, Biden’s defenders shifted first to assert that there’s “no evidence” of Joe’s involvement — and now to insisting there’s “no direct evidence.”

Meanwhile, top White House aide Ian Sams is urging the press to treat all the evidence as “debunked” simply because Sims and other Biden staff have issued statements claiming it doesn’t mean anything.

Pretty soon now, the Biden defense will have to fall back on “no smoking gun” — since that’s all that’s really missing here.

If the president really has nothing to hide, he should stop hiding it.
