The "Pakistani Mystery Man" is Imran Awan, who worked as Rep. Debbie Wasserman Schultz's email server administrator in the House of Representatives. Nearly his entire family then joined the payroll of other Democrats, until they worked for 1 in 5 House Democrats and had - as the House inspector general called it - the 'keys to the kingdom' and ability to access any file.
1. Imran worked for Debbie Wasserman Schultz since 2004 and had the passwords to her devices
A search of his name on WikiLeaks shows the DNC summoned Imran when they needed her device unlocked.
2. During the 2016 election, the House's Office of Inspector General warned that Imran and his family were making "unauthorized access" to data
A September 30, 2016, presentation alleged Imran Awan and his family members were logging into the servers of members who had previously fired him, funneling data off the network, and that evidence "suggests steps are being taken to conceal their activity."
