I just looked at the video clip Schewe posted. It's rather long. But there's some testimony about asbestos from Trump starting at 22:24. I agree with everything he says. He's discussing first how asbestos is a great fire retardant and how many engineers said that the WTC may not have come down on 9-11 if they had used asbestos. But he deferred to the new rules regarding asbestos and then goes on to explain how asbestos abatement can occur in an occupied building and the cost of renovations of buildings.
The point he says that abatement of asbestos can be done in occupied buildings. Of course this is done at night or on weekends. My own experience was I managed renovations in over 250 NYC Public Schools. There are 1200 city-wide in the five boroughs. Most schools are old and had asbestos used during their construction. So when I was involved, asbestos abatement had to be done prior to renovation. Renovations included things like removal and replacements of old coal burning boilers, security camera installations, replacement of walk-in freezers, upgrade of classrooms to modern laboratories, complete renovation of auditoriums, plumbing upgrades, etc. Architects and engineers have to file estimates of how much asbestos would have to be abated with the Building Department before the plans are approved and Work Permits issued. Then, the space has to be abated. Trump describes some of that how it effects tenants. As a renovator of high rise office buildings, hotels, etc. Trump is very familiar with the process which he accurately describes.
Getting back to the OP, the suggestion he's making that some Russian company is exporting asbestos laden construction materials for installation in the US is nonsense. No distributor would handle it. No builder would use it. It’s all illegal to use. Newsweek twisted bits and pieces of testimony like the "fake news media" does all the time to just find a way of knocking Trump.
