The Constitution does not say the Senate has to conduct a fair trial

That is utter BS.

[DrewsMum]

Yes it is. Agree whole heartedly.

He's right. A Senate trial is optional. It is NOT mandatory. The Constitution mandates:

1. The Senate is the only venue allowed to try impeachments

2. That Senators swear an oath for it

3. The Chief Justice of the Supreme Court presides if it is a Presidential impeachment

4. Conviction does not occur unless 2/3 of the Senators present vote for it.

It is up to the Senate to decide whether or not to have an inpeachment trial. They are free to decline to do so, and have actually done it once.
