Conservative author Jerome Corsi filed a criminal complaint against special counsel Robert Mueller at the beginning of December, alleging that investigators tried to coerce him into giving “false testimony” against President Trump. As part of the Russian collusion probe, Mueller's team accused Corsi of acting as a liaison between Trump campaign adviser Roger Stone and WikiLeaks and lying about it. He reportedly sent messages to Stone to find damaging information on Hillary Clinton's campaign. Corsi claims he forgot about the messages, but he didn't lie about them. When he remembered, he amended his testimony.

Corsi would have to admit to "false testimony," or be jailed for the rest of his life, the author's complaint read. Because of the bullying, Corsi wanted the DOJ to investigate Mueller and his minions.

"Special Counsel Mueller and his prosecutorial staff should respectfully be removed from his office and their practice of the law and a new Special Counsel appointed who respects and will obey common and accepted norms of professional ethics and the law and who will promptly conclude the so-called Russian collusion investigation which had been illegally and criminally spinning out of control,” the complaint read.

Now, a few weeks later, Corsi says the harassment was gotten worse. They're targeting his family.

They’re doing door knocks on my stepson, they’re parking surveillance vans with two agents… Harassing my family is beyond bounds." pic.twitter.com/7GBF1oN446 — Trish Regan (@trish_regan) December 27, 2018

"My children have done nothing wrong," Corsi insisted in an interview with Fox Business anchor Trish Regan. Yet, agents have shown up at his stepson's door. They've parked surveillance vans outside the office buildings of his other family members.

"Harassing my family is beyond bounds and I won't stand for it," he said.

President Trump has also called for an investigation into Mueller's tactics. For nearly two years he's dismissed the Russia probe as a "witch hunt." Yet, he denied he would ever demand an end to the investigation.

Analysts predict the larger Mueller probe will last for several more months.
