In Oklahoma, the Tulsa Regional Chamber of Commerce just sort of endorsed Sen. Mary Landrieu (D-LA), but they’re getting some serious flack for it.

Earlier in the month, the Tulsa chamber sent a letter encouraging recipients to attend a Tulsa fundraiser for Landrieu at the home of former Mayor Kathy Taylor, who is vying for her seat against Rep. Bill Cassidy (R-LA). The letter was signed by Tulsa Chamber CEO Mike Neal, who is a very close friend of Landrieu’s husband, Frank Snellings. Neal was even in Landrieus’ wedding party.

Neal’s letter states that Landrieu, as the Chairwoman of the Senate Energy and Natural Resources Committee, “is committed to legislation that is favorable to the industry here in Oklahoma. … I feel that we need to keep Mary in the Senate.”

Now, however, the Tulsa chamber Chairman Wade Edmundson and the state’s Republican delegation is denouncing the chamber’s inadvertent endorsement of Landrieu.

In a response letter to the Tulsa chamber’s letter, the Republican delegation says Landrieu is not, in fact, good for Oklahoma.

“Contrary to the Tulsa Chamber letter, electing Mary Landrieu is not good for American energy policy, Oklahoma business, or the Tulsa region,” the letter states. “Rather, she will keep Harry Reid in charge of the Senate and allow him to continue to block key energy legislation that would benefit our nation, our state, and our region.”

And then, Edmundson responded to Neal’s Landrieu fundraising letter.

Responding to the delegation’s letter, chamber Chairman Wade Edmundson said Neal’s letter was “inadvertently placed” and that the chamber “will take steps to ensure such a mistake does not happen in the future.”

“As Chair of the Tulsa Regional Chamber Board of Directors, it is my duty to stress under no circumstances has the Chamber endorsed this candidate for office,” Edmundson said. “I completely understand the frustration currently felt by our valued friends, members of Oklahoma delegation.”
