At least Donald Trump is still humiliating Chris Christie.

One of the few delights to be found in the Trump era is the way the president constantly humiliates Christie, one of his early Republican supporters. Most of these humiliations seem to revolve around food. A New Yorker article from last June reported a story (which the governor’s office denied) that Trump sent Christie on an errand to pick up Big Macs from McDonald’s. That same month Trump, at a rally, mocked Christie (who was on stage with him) by saying, “You’re not eating Oreos anymore. No more Oreos. For either of us, Chris. Don’t feel bad.”

Now Christie himself has an eyebrow-raising story about dining with Trump at the White House last Tuesday. ‘‘This is what it’s like to be with Trump,’’ Christie said in a radio interview. ‘‘He says, ‘There’s the menu, you guys order whatever you want.’ And then he says, ‘Chris, you and I are going to have the meatloaf.’’’

Trump is a generally joyless figure, but he seems to take genuine pleasure in humbling his fellow politicians. And apparently no one has a greater appetite for being debased than Christie.
