David Pecker, the publisher of several tabloids, including the National Enquirer, Sun, and Weekly World News, used what is called “catch and kill,” which involves a tabloid buying a story from a source and then suppressing it, to keep embarrassing stories about his friend Donald Trump out of the public.

Federal authorities granted Pecker immunity in exchange for his testimony that Trump’s personal attorney Michael Cohen paid him hush money to suppress stories about extramarital affairs involving Trump and former Playboy model Karen MacDougal.

To summarize, one Pecker conspired to protect another pecker’s pecker.

Pecker’s testimony contributed to Cohen’s guilty plea to five counts of willful tax evasion; one count of making false statements to a bank; one count of causing an unlawful campaign contribution; and one count of making an excessive campaign contribution.

Pecker was forced to resign from the board of Postmedia Network Canada Corp, a Canadian newspaper company, after the publicity over his role in the affair concerning Trump and hush-money payments.
