Wednesday began with the national Americans for Prosperity sending out a notice that it did not endorse Republican Congressional candidate Lee Byberg in his bid for the 7th district seat.

The group said it "does not support or oppose any candidate for public office. …Despite multiple attempts by AFP's attorney over several days to contact Byberg's campaign to correct Byberg's claim of endorsement, AFP has received no response."

Byberg's campaign spokesman David Strom said the endorsement note on Byberg's campaign website was placed there in error and the site also mistakenly included mentions of endorsements Byberg got when he ran in 2010.

"We made a mistake," Strom said.

Meanwhile, Gretchen Hoffman, a state lawmaker running against Byberg for the GOP nod, released a statement of her own.

"Lee Byberg owes Minnesota families an apology for his campaign of deception," she said. The endorsement note has since been taken down.
