...All that Article I, Section 3 adds with respect to an official who has been removed through impeachment and conviction is that such an official cannot invoke the Senate conviction as a bar to subsequent criminal prosecution. That such an official “shall nevertheless be liable” to the criminal process says only that he shall “remain” liable to that process—just as he would have been prior to removal. In other words, the impeachment process doesn’t serve as a crime-laundering device...

For reference, from Article 1 Section 3:

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.
