I cannot confirm why Trump is being impeached. I am not inside the majority of House of Representatives minds who voted to impeach.
I believe/feel that since he cannot be removed from office at this point that precluding him from running for any Federal office in the future is important (and can be ordered in an Impeachment trial).
Another important reason for the second impeachment is that with the Republicans no longer in control of the Senate there can be a trial with witnesses who are compelled to testify under penalty of perjury, contempt of Congress, etc, Without the trial some important information about June 6th and its planning may never come to light.
