A Business Summary Brief at 2:39 p.m. EDT combines a regional air alert with a separate report on Donald Trump’s media business. The Massachusetts Department of Environmental Protection issued an Air Quality Alert for fine particulates from midnight on Friday through midnight EDT Saturday night. The agency warns that concentrations of fine particulates in the region may approach or exceed levels considered “Unhealthy for Sensitive Groups,” specifically citing children and adults with asthma or lung or heart disease, as well as older adults, and advising limits on prolonged outdoor activity. Separately, an AP report says Trump may seek to profit from a new Truth Social access tier by charging Wall Street traders for milliseconds-early viewing of posts from “highest-ranking” accounts, potentially including his own. The article notes that White House and Trump’s companies did not comment regarding the proposal.
