The son of Interior Secretary Manuel Lujan Jr. was sentenced Tuesday to 20 years in prison for breaking into a woman's apartment and raping her.

Robert Lujan, 28, of Alexandria, was convicted last month on charges of rape, sodomy and burglary.He was acquitted in Alexandria Circuit Court of using a weapon in connection with those crimes.

During the trial, the defense acknowledged Lujan had sex with the woman, but said it was consentual.
