Whitmer Kidnap Inmates Sue MDOC - Who is listening in to privileged legal calls?

Two men convicted in the 2020 conspiracy to kidnap Michigan’s Gov. Gretchen Whitmer have sued the MDOC for being placed in out-of-state federal prisons, where their ability to communicate with lawyers or prepare their appeals has effectively been eliminated.

The men—Joe Morrison and Paul Bellar—are all incarcerated in federal prisons outside of Michigan, despite the fact that they were convicted of state crimes. Pete Musico is in a similar situation, but his lawyer hasn’t joined the lawsuit.

In the lawsuit, Morrison and Bellar’s attorneys detailed how they haven’t been able to communicate with their clients.

Their lawyers note that a "third party" is listening in to all privileged attorney/client phone calls - GEE, I wonder who that could be?
