My local Congressman's radio ad changed to remove references to Ebola!

I live in Oklahoma and we've had an ad running for a few days advertising Congressman Jim Bridenstein's forum to talk to his constituency about the dangers facing America.

I swear to God the other day in his own words he said these challenges include "ISIS, Russian Aggression and Ebola"

But now the ad has been changed to "ISIS, Russian Aggression and the crisis on the Southern border"

I've heard it 3 times now and it is definitely not an alternate version of the ad but the new replaced one.
