(CNN) On Monday, before the close of the G7 meetings in France, the heads of those nations gathered to talk about climate change and what could be done to address the warming of our planet. Donald Trump didn't go.

"The President had scheduled meetings and bilaterals with Germany and India, so a senior member of the Administration attended in his stead," press secretary Stephanie Grisham said by way of explanation for Trump's absence.

Except that Trump seemed to think -- or at least said -- that the climate change meeting was later in the day and that he hadn't missed it at all. From the pool report:

"Asked if he attended the climate session, Potus says 'we're having it in a little while.' He didn't appear to hear when a reporter told him it just happened."

So, which is it? Did he have other pressing commitments? Or did he think it was later? Or are neither of those things true? (HINT: It's the last one!)
