Trump being into fighting air pollution is a new take I have not heard before. Policy-wise, his administration was vehemently anti-regulation[0] and rolled back many air quality regulations protecting us from toxic substances like coal ash[1], which contains heavy metals like mercury and arsenic.

The most egregious example in my opinion was the attempt to end California's legal authority to set its own, more stringent, emissions standards[2]. The edict was even opposed by a majority of automakers.

Luckily many of these rulings have been rolled-back or are in the process of being reversed.

Air pollution even from tires and brakes, let alone from gasoline, is a large health problem and should be discussed more.
