BREWER QUIETLY FESSES UP…. Just to put a coda on one of the week’s more peculiar stories, Arizona Gov. Jan Brewer (R) conceded she was wrong about immigrants committing beheadings — but she waited until late Friday afternoon on a holiday weekend to fess up.

If you’re just joining us, the odd, far-right governor recently insisted that anti-immigrant legislation in Arizona is necessary, in part because of widespread violence. More specifically, Brewer alleged that immigrants entering the U.S. illegally are responsible for “beheadings” in the Arizona desert, a claim that the governor appears to have just made up out of whole cloth.

State Attorney General Terry Goddard (D), during a debate this week, urged Brewer to admit she was wrong, explaining that the governor wasn’t doing Arizona any favors by lying about crimes that didn’t occur. Brewer refused. After the event, reporters pressed the governor on the point, prompting her to run away.

Late on Friday, Brewer chatted with the AP.

“That was an error, if I said that,” the Republican told The Associated Press on Friday. “I misspoke, but you know, let me be clear, I am concerned about the border region because it continues to be reported in Mexico that there’s a lot of violence going on and we don’t want that going into Arizona.”

First, “if I said that”? She said that.

Second, trying to connect crime to immigration problems is still a losing proposition.

And third, note that Brewer waited until late on a Friday — on Labor Day weekend — to acknowledge the fact that she made up a bogus claim that made her state look bad.

I don’t imagine Arizona voters have heard the last of this.
