It was one of 3 POTUS retweets of @TIME in a row that were the start of a mini tweet storm that took the daily tweet/Qpost count from 110 (6Q rest POTUS) to 123.
All 3 @TIME retweets had a GREEN flavor;
#1 Treasury sec
#2 IRAN (think green in flag
#3 Lincoln/$60000 greenbackers
Now think GREEN for GO
Taken together I think this mini tweet storm tformed a 1, 2, 3, GO command
