CNN preempted Anderson Cooper’s special covering the 10th anniversary of Hurricane Katrina on Tuesday to air a special edition of “CNN Tonight” which went wall-to-wall Donald Trump after his heated exchange with Univision anchor Jorge Ramos during a campaign presser in Iowa.

“Katrina: The Storm That Never Stopped” was scheduled for 9 p.m. ET on Tuesday. Cooper even tweeted to promote it.

Tonight 10 years after Katrina. Check out my @CNNSpecReport #Katrina: The Storm That Never Stopped at 9pET http://t.co/oovF4Hw2lx – Anderson Cooper (@andersoncooper) August 25, 2015

The special didn’t air and has been bumped to Wednesday at the same time.

The #Katrina special report, Katrina: The Storm That Never Stopped has been moved to tomorrow. Wednesday 9pm – Anderson Cooper (@andersoncooper) August 25, 2015

Instead of the Katrina special, Don Lemon and guests reacted to Trump’s barnburner of a speech in Iowa, where he challenged network president Jeff Zucker to pay him $10 million in charity donations to appear in CNN’s presidential debate on Sept. 16.

CNN has not yet returned TheWrap’s request for comment regarding its decision to bump the Katrina special.
