Trump, his son Donald Jr., and others in the Trump organization were given an encryption key to access hacked documents on Wikileaks in an email in September 2016, CNN reports:
The September 4 email was sent during the final stretch of the 2016 presidential race — two months after the hacked emails of the Democratic National Committee were made public and one month before WikiLeaks began leaking the contents of Clinton campaign chairman John Podesta’s hacked emails.
The email came less than three weeks before WikiLeaks itself messaged Trump Jr. and began an exchange of direct messages on Twitter. Trump Jr. told investigators he had no recollection of the September email.
Congressional investigators are trying to ascertain whether the individual who sent the September email is legitimate and whether it shows additional efforts by WikiLeaks to connect with Trump’s son and others on the Trump campaign. The email also indicated that the Trump campaign could access records from former Secretary of State Colin Powell, whose hacked emails were made public by a Russian front group 10 days later.
