AMHERST (CBS) — The University of Massachusetts Amherst launched an independent review into claims against congressional candidate Alex Morse. The 31-year-old Holyoke mayor is accused of pressuring college students into relationships while he worked at the school as a lecturer.

As part of the review, attorney Natashia Tidwell is asking students to come forward to anonymously report any relevant information.

Morse, who is openly gay, has admitted to having relationships with students and apologized to anyone who felt uncomfortable.

Morse’s campaign said the allegations have been engineered to smear his campaign against Congressman Richard Neal in the primary.
