“We regret if the publication of Mrs. Pence’s email address caused any problems,” wrote John Daniszewski, editor-at-large for standards at the AP, in a blog post Monday night.
The controversy began after The Indianapolis Star reported that Mike Pence, a former governor of Indiana, conducted state business on a personal email account that was breached.
In the AP’s story on the hacking, Karen Pence’s personal email address was published.
The second lady said she was subject to “vitriolic and malicious emails,” according to a letter to the Associated Press President CEO Gary Pruitt from Pence's legal counsel.
The vice president then demanded an apology on Twitter.
