Breitbart Texas reports to be that Osteen housed 5000 during Katrina I believe it was. However, these photos have been criticized for making it appear as if Lakewood Church was inaccessible.
Osteen has responded. He is designating his building as a suppllyb station though it is not listed on the official master list of stations.
His palatial residence is making all the rounds, and the closed church.
I am NOT a Joel fan but this is over the top. IIRC, a facility must be certified/approved before flinging open their doors to be a shelter.
