One hundred and ten college and university presidents have issued a joint letter to President-elect Donald Trump urging him to forcefully “condemn and work to prevent the harassment, hate and acts of violence that are being perpetrated across our nation, sometimes in your name, which is now synonymous with our nation’s highest office.”

This action is needed, the presidents write, because of the incidents taking place nationwide, including many on college campuses. “In our schools, on job sites and college campuses, on public streets and in coffee shops, members of our communities, our children, our families, our neighbors, our students and our employees are facing very real threats, and are frightened.”

The full text of the letter and the signatories may be found at the end of this article. (UPDATE: An additional 19 presidents who signed since the letter was first circulated may be found below the original list, and a second group was added on Monday. As more have signed the college has created a website with all the signatures.) News coverage of some of the incidents on college campuses may be found here and here and here. (More than 450 professors at the University of Pennsylvania, Trump's alma mater, have issued an open letter calling on the president-elect to "immediately and publicly denounce" the way three people in Oklahoma signed up black freshmen at Penn to receive text messages with images of violence against black people and racial slurs from someone called "Daddy Trump" or "Heil Trump.")

Mariko Silver, president of Bennington College, led the effort to organize the letter. In an interview, she said the letter came out of discussions she had with fellow presidents, concerned that “our students who have overcome extraordinary adversity” were “feeling anxiety and uncertainty” because of the incidents on campuses.

Silver said students need to hear “from the future leadership of the country” that there is a commitment that they should feel safe from harassment.

Bennington has not experienced the kind of incidents that prompted the letter, Silver said, but she and others are concerned about trends well beyond their campuses.

Trump’s transition office did not respond to a request from Inside Higher Ed to comment on the letter.

In an interview on 60 Minutes shortly after his election, Trump was asked about the incidents of harassment of Muslims, Latinos and others, to which he replied, “I am so saddened to hear that. And I say, ‘Stop it.’ If it -- if it helps. I will say this, and I will say right to the cameras: ‘Stop it.’”

Silver said that comment was positive, but that Trump still needs to truly disavow what has been occurring. She said the message needs to come directly from him.

“One of the roles of leaders is to protect and empower the most vulnerable,” the letter says. “As president-elect, this responsibility rests heavily on you. Let this be a mark of your leadership.”

The vast majority of those who signed the letter lead private institutions, not public ones. Liberal arts college presidents make up most of the signers. Seven presidents lead historically black colleges. One president leads a Canadian university.

Silver said she believed many leaders of public colleges and universities were equally concerned but that they may need to consult with more constituencies before putting their names to such a letter. She stressed that the letter was not an attempt to align the presidents with any political view, and noted that all of the presidents likely have students, alumni and employees who backed different candidates for the presidency.

The text of the letter follows, and the list of signatories follows that.

Letter From Presidents to President-Elect Trump

Dear President-elect Trump,

As do you, we “seek common ground, not hostility; partnership, not conflict.” In order to maintain the trust required for such productive engagement, it is essential that we immediately reaffirm the core values of our democratic nation: human decency, equal rights, freedom of expression and freedom from discrimination. As college and university presidents, we commit ourselves to promoting these values on our campuses and in our communities, and we stand alongside the business, nonprofit, religious and civic leaders who are doing the same in organizations large and small.

In light of your pledge to be “President for all Americans,” we urge you to condemn and work to prevent the harassment, hate and acts of violence that are being perpetrated across our nation, sometimes in your name, which is now synonymous with our nation’s highest office. In our schools, on job sites and college campuses, on public streets and in coffee shops, members of our communities, our children, our families, our neighbors, our students and our employees are facing very real threats, and are frightened.

One of the roles of leaders is to protect and empower the most vulnerable. As president-elect, this responsibility rests heavily on you. Let this be a mark of your leadership.
