The Transportation Security Administration says it's giving all agents in Orlando a refresher course on what a District of Columbia driver's license looks like, after one agent refused to recognize one of them as valid ID.

D.C.-based reporter Justin Gray, who works for Cox Media group, says the agent at checkpoint inside Orlando International Airport "didn't recognize" his license, and asked him to show a passport instead. Gray didn't have one with him.

"At that point, I was a little confused, but then I realized what was going on," Gray later told Orlando ABC affiliate WFTV, "I said to him, 'Do you not know what the District of Columbia is? Washington, D.C.?' After some back and forth, it became clear he didn't."

He got through the checkpoint by escalating the problem to a supervisor.

A spokesperson who contacted Gray after he tweeted about the problem said, "Officers are trained to identify fraudulent documents, which can potentially deter and detect individuals attempting to circumvent this layer of security."

Now they'll also be trained to identify valid documents. At least in Orlando.
