Back in the early days of Hillary Clinton’s campaign, shortly before her official announcement video (and a couple months before her second official campaign kickoff), her campaign manager wondered where his candidate stood on trade.

In an email illegally obtained and released by Wikileaks, Clinton campaign manager Robby Mook was asked if the former secretary of state would be willing to sign onto a letter in support of trade. The letter was presented to Mook by White House aide David Simas, who presented the letter as a bipartisan effort among Republicans and Democrats.
