Former Sens. Tom Daschle (D-S.D.) and Trent Lott (R-Miss.) defended the Senate’s ability to conduct a fair impeachment trial in an op-ed published in The Washington Post on Thursday.

The two noted that while their perspectives differed on what the phrase "do impartial justice" in their impeachment trial oath implied, they both understood the necessity of a trial that would “inspire the confidence of the public and withstand the unsparing scrutiny of history.”

Lott and Daschle also wrote that determining the structure of the trial involved an agreement to ensure that neither side had any “procedural advantage” and providing more rather than less time for debate and testimony, as well as breaks during the deposition process.

“We remain proud that the Senate rose to meet its constitutional duty, and did so in a manner that most observers concluded was fair and impartial,” they wrote.

“If called upon to hold another presidential impeachment trial, we hope senators of both parties will again put aside partisan considerations and approach the task with the same spirit of fairness that served the institution of the Senate and the country so well two decades ago.”

Many of the specifics regarding an impeachment trial are left to the discretion of the Senate, including whether witnesses should testify on the Senate floor or be deposed elsewhere, the length of the trial and how much time each side should have to argue its case.

A nonpartisan trial "is a challenge with a high degree of difficulty, but we believe it can and must be done," the two wrote, noting that in regards to setting such a bipartisan tone early in the process, "not everyone was happy with that outcome. But we heard almost no complaints about the trial itself."
