How the government's punishing of the exposure of official wrongdoing can linger for years

Homeland Security Secretary Janet Napolitano said Wednesday that she didn't order immigration agents to delay arresting an illegal immigrant and registered sex offender working for Sen. Robert Menendez's New Jersey office in the middle of his re-election campaign last year.

Federal immigration agents were prepared to arrest an illegal immigrant and registered sex offender days before the November elections, but they were ordered by Washington to hold off after officials warned of "significant interest" from Congress and news organizations because the suspect was a volunteer intern for Sen. Robert Menendez, New Jersey Democrat, according to internal agency documents provided to Congress.

Sen. Robert Menendez employed as an unpaid intern in his Senate office an illegal immigrant who was a registered sex offender, now under arrest by immigration authorities, The Associated Press has learned. The Homeland Security Department instructed federal agents not to arrest him until after Election Day, a official involved in the case told the AP.
