The Chamber of Commerce, the national pro-business group that typically backs GOP candidates, is reportedly planning to endorse Democratic Sen. Mary Landrieu (La.) for reelection.

According to New York Times columnist Joe Nocera, at its most recent meeting of regional chamber and trade association leaders, the Chamber’s Political Director Rob Engstrom told attendees the group plans to back Landrieu this cycle.

Engstrom told The Hill via text message, however, that the Chamber’s verdict on the Louisiana Senate race was still out.

“No decisions ‎have been made in the LA Senate race,” he said.

Though the Chamber bills itself as bipartisan, it has increasingly backed Republicans over the years, but the Landrieu endorsement isn’t quite a surprise — the group backed her for reelection in 2008.

But it could put the Chamber at odds with the GOP’s goal of taking back the Senate. Landrieu is considered perhaps Democrats’ most vulnerable incumbent at this point in the cycle, and the GOP’s path to picking up the six seats it needs to flip the upper chamber winds through Louisiana.

She’s facing a top-tier GOP recruit in Rep. Bill Cassidy, as well as a challenge from retired Air Force colonel Rob Maness.
