Trump's Twitter account posts its first tweet promoting Trump University

On July 28, 2009, the @realDonaldTrump account, launched that May, posted: "Check out a list of Donald Trump's books for summer reading at the Trump University Blog" — the account's first tweet to name Trump University, per the timestamped tweet archive (only one other 2009 tweet, on August 4, mentions the venture). Trump University was at the time actively selling real-estate seminars; roughly 7,600 course tickets were sold during its 2005-2010 run. New York's attorney general later alleged in a 2013 suit that the operation was a "bait-and-switch scheme" that misled students into paying up to $35,000, claims Trump resolved in November 2016 with a $25 million settlement covering about 7,000 former students. The tweet itself is routine promotion, and the event is rated minor; its significance is as the earliest documented use of Trump's new Twitter channel to market the venture. Date and text are exact, drawn verbatim from the raw @realDonaldTrump tweet corpus (id 2891870497, Tue Jul 28 15:50:31 +0000 2009).
