PROVIDENCE, R.I. — The Brown University campus newspaper apologized Wednesday after publishing what it says were two “deeply hurtful” and racist columns.

The Brown Daily Herald’s editorial board published an editor’s note saying it regretted the hurt caused by the two opinion columns, both written by student M. Dzhali Maier.

One titled “The white privilege of cows,” which was published Monday, “invoked the notion of biological differences between races,” while “Columbian Exchange Day,” published Tuesday, argued that Native Americans should be thankful for colonialism, according to the editor’s note.

“The white privilege of cows” column was left on The Herald’s website “in an effort to be transparent,” according to an editor’s note later added to it. The “Columbian Exchange Day” column was removed and replaced by an editor’s note.
