Dear Senate colleagues,
As former members of the U.S. Senate, Democrats and Republicans, it is our shared view that we are entering a dangerous period, and we feel an obligation to speak up about serious challenges to the rule of law, the Constitution, our governing institutions and our national security.
We are on the eve of the conclusion of special counsel Robert S. Mueller III’s investigation and the House’s commencement of investigations of the president and his administration. The likely convergence of these two events will occur at a time when simmering regional conflicts and global power confrontations continue to threaten our security, economy and geopolitical stability.
It is a time, like other critical junctures in our history, when our nation must engage at every level with strategic precision and the hand of both the president and the Senate.
We are at an inflection point in which the foundational principles of our democracy and our national security interests are at stake, and the rule of law and the ability of our institutions to function freely and independently must be upheld.
During our service in the Senate, at times we were allies and at other times opponents, but never enemies. We all took an oath swearing allegiance to the Constitution. Whatever united or divided us, we did not veer from our unwavering and shared commitment to placing our country, democracy and national interest above all else.
At other critical moments in our history, when constitutional crises have threatened our foundations, it has been the Senate that has stood in defense of our democracy. Today is once again such a time.
Regardless of party affiliation, ideological leanings or geography, as former members of this great body, we urge current and future senators to be steadfast and zealous guardians of our democracy by ensuring that partisanship or self-interest not replace national interest.
