Assemblyman Mike Cole admitted spending the night at the female intern's apartment. The New York Post reported Cole, a married father of two, said he slept on her floor because he was too drunk to drive home after watching the NHL playoffs with a group of interns.
The intern, who worked for another legislator, has been fired.
A letter of admonition from Assembly Speaker Sheldon Silver said Cole's behavior "exhibited a profound lack of respect or appreciation for the appropriate and positive role the policy envisions for members of the Assembly with respect to student interns," the Post reported.
An ethics investigation found that Cole had violated a policy against fraternization with interns.
