The editorial board of the Whitter Daily News is taking heat from local activists after the newspaper posted an ''erroneous" City Council campaign endorsement online, then substituted a corrected version overnight.

On Thursday afternoon, the paper posted a Web editorial that backed council challengers Nick Donovan, Lupe Sahagun Garcia and Craig Lebow, all of whom oppose an oil company’s controversial plan to drill for crude within the city limits.

“They collectively question whether Whittier will ever see a windfall from oil revenues and are suspicious of the oil industry in general, and rightly so,” the endorsement said.

However, that online endorsement was changed Friday.

“Editorial boards, like voters at the ballot box, sometime change their minds," the updated endorsement read. "Initially we crafted an editorial Thursday endorsing the three challengers in Tuesday’s City Council election. After careful reconsideration, we decided to back incumbent Joe Vinatieri along with Craig Lebow and Lupe Sahagan-Garcia [sic]. The initial endorsement was erroneously posted online.”
