An Energy Department appointee resigned Thursday amid controversy stemming from comments he made online and later claimed were the result of hacking.

CNN reported that William Bradford, the director of the Energy Department's Office of Indian Energy, stepped down just two days after the news network reported on inflammatory comments from a user appearing to be Bradford on the online commenting service Disqus.

Bradford told CNN that the comments were the result of "cyber attacks and Internet crimes" that had been going on for several years.

The comments called former President Barack Obama's mother a "fourth rate porn actress and whore."

Another comment contends that Obama's birth certificate is "an obvious fake."

Bradford came under fire for online behavior in June, after posting offensive tweets, including one suggesting that Obama received a "mission from Tehran" and calling him a "Kenyan creampuff."
