Last week, multiple liberal news sites were forced to correct false stories claiming Rep. Michele Bachmann (R-Minnesota) called for "Americanization facilities" for undocumented migrants at the border.

The sites — including ThinkProgress and Crooks and Liars — based the story on a parody site called KCTV7 News that features clearly absurd stories on its home page. For example, one KCTV7 news story is titled, "Feds Spend $2.2 Million To Study Why Lesbians Are Obese."

As Raw Story pointed out on Sunday, KCTV7 appears to have copied the story from another joke site, the National Report, which published it two weeks ago.

Both outlets retracted their stories after publication and apologized for being duped.

"We sincerely regret the error," ThinkProgress wrote, doing a complete strike through the text of the original article.

Crooks and Liars argued Bachmann's outspoken conservatism made the parody believable.

"Yeah, I got pwned," the author wrote. "How sad is it that it was just this side of realistic enough to believe in the first place. When you have a reputation for making outrageous and ridiculous comments, it becomes easier and easier to believe something that should have been dismissed out of hand."

Bachmann's office did not immediately respond to a request for comment from Business Insider.
