Alumni and faculty at Sen. Susan Collins’ alma mater are demanding the university revoke an honorary degree she received last year after she voted to confirm Supreme Court Justice Brett Kavanaugh.

More than 1,800 alumni and dozens of staff members at St. Lawrence University are sending letters to the college on Tuesday calling for the revocation of the honorary degree, according to CBS News. Collins, R-Maine, graduated from the northern New York university in 1975.

More than 1,300 alumni and current students signed a letter to the university earlier this month that said Collins’ support of Kavanaugh “is not in line with the core values” of the university.

“At the time she was nominated she was being recognized as a senator who was willing to break party ranks to protect The Patient Protection and Affordable Care Act (ACA). Her decision to stand for what she saw as the greater good embraced the strong values of St. Lawrence University,” the letter said.

Another message signed by faculty said rescinding Collins’ 2017 honorary degree would help “dismantle rape culture” on campus.

“While our campus has come a long way in the years since Senator Collins was a student here to educate the campus population about sexual assault and harassment, and to adjudicate it fairly when it happens, we still have much hard work before us in and outside of the classroom,” university faculty wrote.

University spokesman Ryan Deuel said the university had no plans to rescind Collins’ honorary degree.

"Throughout its long history, St. Lawrence University has never rescinded any earned or honorary degree, and it has no intention of doing so in this situation," Deuel told CBS News.
