A Philadelphia law school professor says she was "mortified" when she discovered that she had inadvertently sent students a link to a porn site rather than an article about writing legal briefs earlier this month.

Professor Lisa McElroy teaches legal writing and teaching methods at Drexel University's law school. She said in an op-ed Friday in The Washington Post (http://wapo.st/1JF5ncS) that she cares deeply about her students and university and about being a role model for her adolescent daughters.

But McElroy called the incident "pretty trivial" and criticized what she called "tabloid journalists" who ran with the story. She said there are worse things than humiliation, including, as she put it, "the willingness — even the desire — to bring others down to lift yourself up."

A university representative did not immediately return a phone message Sunday.
