A teaching assistant at the University of Iowa accidentally instead of "accidently," which isn't really a word. dl *ok MR e-mailed naked photographs of herself and a man to students. She had intended to send an attachment with answers to some questions on a problem set. As news of the e-mail embarrassment spread on social media, the university asked those who received the e-mail to delete the message and to not share the files with anyone else. The incident was “inappropriate” and the university will look into it and take appropriate actions under its policies and procedures, a spokesman said. He said that the teaching assistant regrets what happened.
