President Donald Trump has nominated David Keeling to head the Occupational Safety and Health Administration (OSHA), a move that has sparked controversy due to Keeling’s past employment with UPS and Amazon. Both companies have been vocal opponents of OSHA’s proposed heat safety regulations, which aim to protect workers in extreme weather conditions. The nomination has raised concerns about potential conflicts of interest, as Keeling’s previous employers have actively resisted the implementation of these safety measures.
