Donald Trump mentions 'Pakistani mystery man' in his tweet after Democrats file suit

Shortly after the  Democratic National Committee filed a multimillion-dollar lawsuit Friday against the Russian government, the Trump campaign and the WikiLeaks organization alleging a far-reaching conspiracy to disrupt the 2016 campaign and tilt the election to Donald Trump, the US president took to Twitter to respond.

"Just heard the Campaign was sued by the Obstructionist Democrats. This can be good news in that we will now counter for the DNC Server that they refused to give to the FBI, the Debbie Wasserman Schultz Servers and Documents held by the Pakistani mystery man and Clinton Emails," he said.

It was not immediately clear what Trump meant by his comment or who he was referring to.
