The allegations made in the articles of impeachment are very serious. As a senator-juror, I swore an oath before God to exercise impartial justice. I am profoundly religious. My faith is at the heart of who I am. I take an oath before God as enormously consequential. I knew from the outset that being tasked with judging the president, the leader of my own party, would be the most difficult decision I have ever faced. I was not wrong.

The House managers presented evidence supporting their case, and the White House counsel disputed that case. In addition, the president’s team presented three defenses, first that there could be no impeachment without a statutory crime, second that the Bidens’ conduct justified the president’s actions, and third, that the judgment of the president’s actions should be left to the voters. Let me first address those three defenses.

The historic meaning of the words “high crimes and misdemeanors,” the writings of the founders and my own reasoned judgment convince me that a president can indeed commit acts against the public trust that are so egregious that while they’re not statutory crimes, they would demand removal from office. To maintain that the lack of a codified and comprehensive list of all the outrageous acts that a president might conceivably commit renders Congress powerless to remove such a president defies reason.

The president’s counsel also notes that Vice President Biden appeared to have a conflict of interest when he undertook an effort to remove the Ukrainian prosecutor general. If he knew of the exorbitant compensation his son was receiving from a company actually under investigation, the vice president should have recused himself. While ignoring a conflict of interest is not a crime, it is surely very wrong. With regards to Hunter Biden, taking excessive advantage of his father’s name is unsavory, but also not a crime. Given that in neither the case of the father nor the son was any evidence presented by the president’s counsel that a crime had been committed, the president’s insistence that they be investigated by the Ukrainians is hard to explain other than as a political pursuit. There’s no question in my mind that were their names not Biden, the president would never have done what he did.

The defense argues that the Senate should leave the impeachment decision to the voters. While that logic is appealing to our democratic instincts, it is inconsistent with the Constitution’s requirement that the Senate, not the voters, try the president.
