Exactly. The House makes their case, they don't demand the Senate make up for their failures.
The House only is required to make their case on whether CHARGES need to be brought, as with prosecutors....they simply make charges against someone....
The Senate and a court room, is where the Managers or prosecutors have to PROVE they committed a crime or high crime and or misdemeanor in impeachment.... in a court trial, the prosecutor has to prove beyond a reasonable doubt that the person is guilty, in an impeachment trial, it is also a higher bar than what it took for the house to make charges in their articles of impeachment... this is why all evidence and any new evidence is ALWAYS allowed in a trial..... EXCEPT THIS SHAM TRIAL.
Except. There ONLY reason there ware any new witnesses at all was the House's incompetence in getting them.
Nope The new witnesses, including Bolton, AFTER the impeachment leaked out what was in his book about the Ukraine scandal, making it clear that he did have a specific connection with the scandal. This did not happen when they were calling Bolton and his assistant in the House Inquiry, they were searching to see if there were any connections of them and the Ukraine, so when they went the court route, they dropped it, because it would take years, and they did not even know they would Net anything.
but AFTER the impeachment had been done, is when the new evidence came out that Bolton had a first hand connection.
Same with Parnus, AFTER the impeachment, a court ruled that all of Parnus's emails that the SDNY had subpoenaed, could be released back to Parnus, so he could turn them over to the impeachment managers and investigators... the court's ruling to give Parnus the OK came after impeachment but before the trial....
Also, on the subpoenas the House issued for emails and documents that the Whitehouse and agencies refused to turn over.... many were released to a non profit watchdog agency via a Freedom of Information Act FOIA request..... and those were made public and gotten AFTER the impeachment but before the trial... not through their subpoena, but through the FOIA request of an outside group....
