For more than 90 minutes last week, Donald Trump gave a rambling speech accepting the Republican nomination for president for a third time. He used the opportunity, as well as his June debate with President Biden, to repeat favorite false claims and exaggerations. That Mr. Trump has a proclivity for saying untrue things is well known. But in his latest campaign for the White House, I’ve been struck by what appears to be an escalation in both the frequency of Mr. Trump’s lies and the outrageousness of his distortions.

Now that the uncertainty around Mr. Biden’s candidacy has been resolved, the campaign will begin anew. With Mr. Trump sure to ratchet up his falsehood-laden rhetoric, it’s a good time to review his recent record of dishonesty.

Lie: “The only jobs [President Biden] created are for illegal immigrants and bounce-back jobs — they’re bounced back from the Covid.”
