From the editorial board of the Washington Post:
Polls show that Americans overwhelmingly want the trial to hear witnesses. There is no precedent for an impeachment trial without live testimony. If it suppresses it, the Senate will ratify a coverup, making any acquittal of Mr. Trump meaningless.
Mr. Trump tried to use his office to force Ukraine to intervene in the 2020 election. He and his lawyers have not only refused to admit wrongdoing, but have brazenly asserted the president’s right to engage in such manipulations.
If that proposition is the one to be decided, and what should be a full and fair trial is aborted on the president’s orders, the only justifiable vote will be for conviction.
