He did blame the WTC collapse on there not being asbestos on the support structures but he was pro asbestos before. He blamed the abatement companies for being mobbed up in "The Art of the Comeback" in 1997
I believe that the movement against asbestos was led by the mob, because it was often mob-related companies that would do the asbestos removal. Great pressure was put on politicians, and as usual, the politicians relented. Millions of truckloads of this incredible fireproofing material were taken to special “dump sites” because of this stupid law
