Sen. Lamar Alexander Says He's A No For Impeachment Trial Witness Vote

The transcript discusses the Senate impeachment trial of President Donald Trump, focusing on the likelihood of the measure to call witnesses or documents failing. Senator Alexander, a key swing vote, decided against additional evidence, stating it was unnecessary. Some Republican senators, including Mitt Romney, Susan Collins, and Lisa Murkowski, showed some support for more testimony, but four Republican votes are needed to pass the measure. Without new evidence, the trial could conclude soon, with Chief Justice John Roberts unlikely to intervene in a tie.
