From the Introduction: "This is a moment of national emergency. One that comes with a unique set of challenges. Americans are being asked to stay home. Americans are being asked to socially distance themselves from their neighbors, colleagues, friends, and even family. Yet others are being asked to put themselves at risk to take care of the sick, protect their communities, and keep the supply chains running. Likewise, Congress must be prepared to do the urgent work of responding to the massive challenges we face as a country. That work must proceed thoughtfully, while keeping public safety at the forefront and at the same time preserving the integrity of the institution. Since the onset of the COVID [coronavirus]-19 pandemic, the Rules Committee has heard from Members who want to come back to Washington and vote on critical legislation, and Members who want to implement remote voting due to concerns Congress will be unable to pass legislation while also protecting the health of Members, staff, and the public. While these concerns are completely valid, implementing remote voting would raise serious security, logistical, and constitutional challenges."
