From the Mueller Report:
“In late July 2016, soon after WikiLeaks’s first release of stolen documents, a foreign government contacted the FBI about a May 2016 encounter with Trump Campaign foreign policy advisor George Papadopoulos. Papadopoulos had suggested to a representative of that foreign government that the Trump Campaign had received indications from the Russian government that it could assist the Campaign through the anonymous release of information damaging to Democratic presidential candidate Hillary Clinton. That information prompted the FBI on July 31, 2016, to open an investigation into whether individuals associated with the Trump Campaign were coordinating with the Russian government in its interference activities.”
Investigations by agents of law enforcement are properly responsive to complaints from individuals, corporations or even other governments that become aware of nefarious behavior. Typically, informants and investigations are confidential to protect the reputations of innocent persons AND prevent retaliation against the sources of information. Typically, the targets of investigation are also confidential until evidence suggests they should be charged. Which, at a minimum, tells us that whatever the POTUS’ intent, his efforts to publicize the on-going investigation by the Special Counsel was highly inappropriate.
To impeach is to challenge a person’s honesty. A vote of no confidence does the same.
