As national security professionals, many of us have long been concerned with President Trump’s actions and their implications for our safety and security. Some of us have spoken out, but many of us have eschewed politics throughout our careers and, as a result, have not weighed in publicly.
The revelations of recent days, however, demand a response. Specifically, all of us recognize the imperative of formal impeachment proceedings to ascertain additional facts and weigh the consequences of what we have learned and what may yet still emerge. We applaud those Members of Congress, including Speaker Pelosi, who have now started us down that necessary path.
President Trump appears to have leveraged the authority and resources of the highest office in the land to invite additional foreign interference into our democratic processes. That would constitute an unconscionable abuse of power. It also would represent an effort to subordinate America’s national interests—and those of our closest allies and partners—to the President’s personal political interest.
Having worked across administrations of both parties to uphold and advance those national interests, we consider the President’s actions to be a profound national security concern. Our relations with the rest of the world and our policies on the global stage must be based solely on what is in the national interest. The introduction of any other considerations of the President debases our democracy, has the potential to make us more vulnerable to threats, and sends a message to leaders around the world that America’s foreign policy can be dangerously corrupted by catering to a single individual. If we fail to speak up—and act—now our foreign policy and national security will officially be on offer to those who can most effectively fulfill the President’s personal prerogatives.
To be clear, we do not wish to prejudge the totality of the facts or Congress’ deliberative process. At the same time, there is no escaping that what we already know is serious enough to merit impeachment proceedings. From there, the facts—and nothing but the facts—should dictate how Congress holds the President to account and signals to the world that our foreign policy and national security are not for sale.
