Rep. Steve Rothman (D-9th Dist.) took the action after learning that Robert Decheine was among 11 people snared in a Gaithersburg, Md., police sting. Police placed ads on a website and an undercover officer communicated with customers through phone and text messages.
Police said the 48-year-old was arrested on Nov. 17 after soliciting to have sex with an underage girl. Decheine was released on $15,000 bail.
The Record newspaper reports Rothman's office issued a statement saying the New Jersey Democrat considers the alleged criminal act "to be shocking, appalling and indefensible."
Decheine told the newspaper in an e-mail message he had no comment
Decheine has run Rothman's Washington and New Jersey offices since May 2003.
