I though [19] meant number of minutes between POTUS tweets. One I have found so far is a reminder to watch Ivankas Interview on F&F on Dec. 18th.

And he immediately tweets

New Wikileaks tweet. Exactly 19mins after POTUS tweet. Just now

Someone explain the significance of CNN retraction of story about POTUS and Wikileaks.

Did everyone miss the POTUS tweet followed by Wikileaks tweet 19 mins apart just now

Then on Dec 9th tweets 19mins apart. About a huge mistake made by CNN
