Oh. to the contrary. When one reads the Congressional Research Report, Impeachment and the Constitution it confirms the very purpose of impeachment was to deal with one holding a federal office of public trust, who violates that trust and commits criminal acts, such as bribery, that are related to his office of public trust.
“While evidence of precisely what conduct the Framers and ratifiers of the Constitution considered to constitute high crimes and misdemeanors is relatively sparse, the evidence available indicates that they considered impeachment to be an essential tool to hold government officers accountable for political crimes, or offenses against the state. 70 James Madison considered it “indispensable that some provision be made for defending the community against incapacity, negligence, or perfidy of the chief executive,” as the President might “pervert his administration into a scheme of peculation or oppression,” or “betray his trust to foreign powers.” 71 Alexander Hamilton, in explaining the Constitution’s impeachment provisions, described impeachable offenses as arising from “the misconduct of public men, or in other words, from the abuse or violation of some public trust.” 72 Such offenses were “POLITICAL, as they relate chiefly to injuries done immediately to the society itself.” 73 These political offenses could take innumerable forms and simply could not be neatly delineated. 74”
I am of the opinion that the first step to deal with Sen. Menendez is to have the Senate convict him of the charges, which then opens the door for him being "… liable and subject to Indictment, Trial, Judgment and Punishment, according to Law", and in a federal district court as per Article I; Section 3, Clause, 7:
”Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States: but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law."

Why have a written constitution, approved by the people, if those who it is meant to control are free to make it mean whatever they wish it to mean?
