When it comes to the economy, it’s becoming uncomfortably apparent that in many cases, self-described “incredible” businessman Donald Trump either has no idea what he’s talking about or he’s lying. Last week, we learned that he called erstwhile national security adviser Mike Flynn at 3 A.M. with questions about how the dollar works. Over the weekend, it was National Economic Council director Gary Cohn who had to explain that the administration’s big infrastructure plan will actually cost money. Today’s revelation comes courtesy of Federal Reserve chair Janet Yellen, whose testimony before Congress might as well have simply been “Donald Trump is full of sh*t.” Per CNBC:

During testimony before Congress, the central bank leader was asked if businesses have access to capital. Senator Elizabeth Warren of Massachusetts asked Yellen specifically about remarks from Trump alleging that banks are not lending because of financial reforms adopted after the 2008 financial crisis. Yellen said commercial and industrial lending specifically surged after the crisis, rising 75 percent since 2010, the year Dodd-Frank was passed.

“They’re lending,” Yellen said in response to an earlier question from Senator Sherrod Brown, an Ohio Democrat. “Their price-to-book ratios are substantially higher than the ratio of banks headquartered in other areas, and they're gaining market share, and they remain quite profitable.”

Yellen also told Brown, “Lending has expanded overall by the banking system, and also to small businesses,“ and, in response to a question about how U.S. banks are doing relative to their competitors abroad, she said, “U.S. banks are generally considered quite strong relative to their counterparts. They've built up quite a bit of capital, partly as a result of our insistence that they do so.”

That insistence, of course, came via Dodd-Frank, which Trump recently knee-capped by way of an executive order. Dodd-Frank, Trump explained on the morning that he signed the order, had imposed onerous requirements on his “friends”, he said, preventing them from borrowing the money they need for their “nice businesses.” He knew this, he said, because JPMorgan C.E.O. Jamie Dimon had told him so.

Yellen, you may recall, was subject to claims by Trump during his campaign that she was in cahoots with Barack Obama to create a “false stock market” to make the president look good. So it’s certainly conceivable that today’s fact-checking exercise won’t be well-received.
