For John, BLUF: I think this comes from the Obama years. Nothing to see here; just move along.
This is about New You Times Reporter Maggie Haberman.  She is the White House Correspondent for The Old Gray Lady. She tweeted:
Other than San Bernardino shootings, has there been a terrorist attack involving a non-US-born attacker since 9/11?Ms Haberman was up late, as this was date stamped 9:23 PM - 27 Jan 2017, from Brooklyn, NY.
Someone asked why we use 9/11, rather than 9/10 (or some earlier date)?
Oh, amongst others, there are the Tsarnaev Brothers (Boston Marathon Bombing).
Several people responding suggested The New York Times invest money in Google Accounts for their Reporters.
Hat tip to the InstaPundit.
