(CNN) – Penn State has had its share of controversy for a while, but this week it is getting some more unwanted attention.
The university's Chi Omega sorority chapter is under investigation after a photo with Mexican stereotypes surfaced on a social media site.
It shows a group of sorority members dressed in ponchos and sombreros and wearing fake mustaches. One woman holds a sign that says: "Will mow lawn for weed + beer." Another sign says: "I don't cut grass. I smoke it."
The photograph was taken at a Mexican-themed party around Halloween, according to the independent college blog, Onward State. It was posted last week on Tumblr.
