(CNN) -- The Wisconsin prosecutor at the center of a texting scandal has retained an attorney, and is on medical leave, according to the Calumet County District Attorney's office.
District Attorney Ken Kratz apologized Friday for sending personal texts to a domestic abuse victim while prosecuting her former boyfriend, but said he won't step down from office.
Wisconsin Department of Justice officials said some of Kratz's texts "cross the line and can be construed as sexual harassment."
They cited a specific text that refers to the woman as a "tall, young, hot nymph," and another that says, "You are beautiful and would make a great partner someday."
E-mails from November 2009 between Kratz and the Wisconsin Department of Justice show Kratz denied wrong-doing for weeks before finally saying, "My behavior was inappropriate."
During his press conference on Friday, Kratz also said he intended to stay in office "as I have been elected to do," and that he had already seen a psychotherapist, but may consider taking personal time off to seek additional treatment for this issue.
Calumet County's statement said, "the length of the leave at this time is undetermined," and that "all inquiries regarding office function should be directed to Assistant District Attorney Jeffrey Froehlich."
In recent months, several local and state domestic violence organizations have called on Kratz to resign as district attorney.
"There is no way any victim can have trust in that office," said Beth Schorr, executive director of Harbor House Domestic Abuse Programs in Calumet County. She said she stands behind a statement from the Wisconsin Coalition Against Domestic Violence, which said Kratz "attempted to minimize and mislead" regarding the matter.
E-mails between Kratz and the state's Department of Justice suggest Kratz sent 30 text messages over a three-day period to the woman, who later contacted local police and "expressed concerns that if she did not do what [Kratz] wanted her to, [Kratz] might throw her case or possibly retaliate in other ways," according to the Wisconsin Justice Department.
After the incident became public, Kratz resigned his position as chairman and district appointee to the Wisconsin Crime Victims Rights Board in December of 2009.
Officials have said previously that Kratz did not violate the law or any rules of professional conduct, but said his conduct was "inappropriate" and "could easily have adversely impacted his ability to successfully prosecute his case on behalf of the state."
Kratz, in his appointment to the CVRB in 1998, drafted statute Ch 950, which states that "crime victims are to be treated with dignity, respect, courtesy and sensitivity and that prosecutors are to honor and protect the rights of crime victims," said Wisconsin Justice Department officials.
