U.S. District Judge Samuel Kent, the first federal jurist indicted on sex crimes, is now facing more serious charges.

Kent was set to be arraigned Wednesday, a day after a federal grand jury in Houston added three new charges to the indictment it issued in August that accuses him of making unwanted sexual advances toward his former court case manager.

The new charges — aggravated sexual abuse, abusive sexual contact and obstruction of justice — allege Kent engaged in unwanted sexual contact with a second former court employee and later lied about it to investigators.

"There is a gag order in the case which prohibits the parties from making any sort of comment with the exception of stating without elaboration what the defense is to these new charges," said Dick DeGuerin, Kent's attorney. "They are untrue and we believe the product of intense pressure and threats brought against the complainant."

In a press release, the Justice Department only gave a brief description of the additional charges against Kent.

Kent, who was released on his own recognizance after last year's indictment, is still on the bench.

Jury selection in Kent's trial on the initial charges against him was set to begin Jan. 26. It was not immediately known if the new charges would delay the trial.

If convicted, Kent faces up to life in prison and a fine of up to $250,000. He is the first federal judge to be indicted in the last 18 years.

Kent initially faced two counts of abusive sexual contact and one count of attempted aggravated sexual abuse following a U.S. Justice Department investigation into complaints by case manager Cathy McBroom.
