Arizona Sen. John McCain has raised issues over the recent redefining of sexual harassment in the context of university campuses.

In a letter to U.S. Attorney General Eric Holder about a recent settlement agreement the government reached with University of Montana-Missoula over the enforcement and application of Title IX of the Education Amendments of 1972, McCain wrote the settlement was “troublesome that significant changes to nationwide sexual harassment policy were unilaterally dictated by DOJ…”

The senator continued: “In short, Assistant Attorney General Perez and DOJ have used a settlement to effectively change the law, avoiding public accountability for their actions.”

McCain said the settlement poses potential constitutional issues for college students and teachers.
