Don’t determine guilt or innocence; only if trial was held by the Senate.
Explanation:
According to the Federal Constitution, Article 1, Section 3, the US Senate has the sole powers to try impeachment cases. Just determining a person guilty or innocence will not end a judgment case, it is trial of the Senate that decides the fate in judgment cases.
Judgment of impeachment cases can disqualify and remove a member from the official duties, trust, profit, honor under the United States. Such a member is also liable to judicial indictment and trial and legal punishment.
The Senate with the House of Representatives as Grand Jury members holds the trial to prove guilt or innocence. If anyone is found guilty of impeachment, the Article of Impeachment is voted first by the Judiciary committee, and then by all the members of the House and a majority of 2/3rd votes are required.
