Senator Crowder was accused by Susan Lontine, a Democratic State Representative from Denver, of pinching her buttocks and making sexually inappropriate comments while on the House floor. He apologized, though he did not take steps to acknowledge or change his behavior. Colorado State Senate President Republican Kevin Grantham issued a statement when the story was published, saying, "We take every allegation of harassment or misconduct seriously. We ask those who feel they have been victims of harassment or inappropriate behavior at the General Assembly to file an official complaint, in confidence that their anonymity and rights will be protected. Going forward, Senate Republican leaders cannot and will not be responding to unsubstantiated or anonymous allegations against members appearing in the press, which the existing complaint process is designed to handle. This process exists to protect confidentiality, respect the rights of both accuser and accused, rigorously review the facts, give a fair hearing to all sides, and impose penalties proportionate to any confirmed offense."
