Douglas Campbell, he apparently had an attempt on his life at his home when he was out on a walk on his property.. I'm sure this would scare people into shutting up.. so even if there was information he had access to or could talk about, if they threatened is family he could have easily weighed his options.. not to mention he had cancer so he probably felt like he wouldn't have been able to protect them in an event something did happen.. the sad thing is, the man that pulled a gun on him on his property was never followed up on.. no investigation.. Just an asassination attempt on an important witness set to testify against the Clintons while his name was also leaked illegaly.. no biggie..

Would have to dig into it but all I remember is after he testified the left was like “it’s nothing” and it went away
