"They're shorts, I promise," Reeve answered back in a tweet.
Later on Twitter, Reeve explained his casual attire.
"Trying to be efficient I got ready for a post-GMA workout a little too soon this morning," Reeve tweeted. "The camera angle, along with friends, family, and several hundred strangers on the social media made me rethink my morning routine. Any sartorial tips from these people who are wearing a belt, trousers and shoes during their work video calls at home are most welcome. Now, back to work. Wearing pants."
It’s not the first time an ABC News correspondent did a report in his shorts. Peter Jennings, reporting from Cairo, did his camera standup in a formal coat. But when the segment was over, the cameraman panned down, to reveal Jennings’s untucked shirt covering his bare legs. The moment is captured on YouTube (skip ahead to the 2:16 mark).
