It's not difficult language to understand. Trump isn't in office, which is why the Chief Justice refused to participate. If this was a serious case, then this avenue shown in bold below would be pursued:
There are some problems with your attempt to read the US Constitution.
When the President of the United States is tried, the Chief Justice shall preside...
1. Trump was no longer the President as of Jan 20, 2021. The Chief Justice only presides for a President. Trump is not President so this does not apply. Your argument ignores the reality of who is President and therefore ignores what the meaning of the US Constitution. Any honest reading of this text would show that anyone that is not the current President is being tried it doesn't require the Chief Justice.
The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.
2. Trump is not President so the penalty of being removed from office doesn't apply. This statement nowhere claims that only those people listed can be impeached. It only gives us the penalty someone holding office must receive if convicted. Since Trump is not a President the section doesn't apply since he can't be removed from office.
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.
3.You don't get to ignore the subject of a sentence when trying to interpret the meaning of the sentence. Judgement is the subject of the sentence. That judgement is then modified to say it can't be further than a total of 2 options. There is no requirement that both options occur. There is also no requirement that even one of the options has to occur.
Meanwhile you completely ignore this part of the US Constitution -
The Senate shall have the sole Power to try all Impeachments.
We are left with the word "all" here which has a very specific meaning which is pretty easy to understand. It means the Senate has the power to try each and every impeachment. There is no exception for impeachments where the person impeached is no longer in office.
It seems you do have difficulty with language and words.
Words and phrases that you can't seem to understand - "President", "shall not extend further than", and "all."
