In November, the New York Times revealed that Clinesmith was under criminal investigation for allegedly doctoring materials used to obtain renewals of the Carter Page surveillance warrant. Clinesmith -who worked on both the Hillary Clinton email investigation and the Russia probe, was part of Special Counsel Robert Mueller's team, and interviewed Trump campaign advisor George Papadopoulos.

Clinesmith, a 37-year-old graduate of Georgetown Law, "took an email from an official at another federal agency that contained several factual assertions, then added material to the bottom that looked like another assertion from the email's author, when it was instead his own understanding," according to the report.
