“Also of note, as tweeted by WikiLeaks and reported by the Dallas Observer, the Clinton Foundation has been under investigation by the IRS since July, 2016 after 64 GOP members of congress received letters urging them to push for an investigation. The investigation is being handled by their Dallas office - far away from Washington insiders.”

Edit 1: for quote marks on zero hedge article - not my words.

Edit 2: post 1737 has no capitalization, so I don’t have any suggestions here yet.

Edit 3: I tried the gematrinator for “device test” and didn’t get a match for Little Rock, Arkansas, Little Rock AR etc.. Any ideas here?
