The US government has appointed a former department of transportation (DOT) official as an envoy to work with ports on vessel congestion and supply chain disruptions brought on by Covid-19 and recovering consumer demand.

John Porcari, former deputy transportation secretary under the administration of then-president Barack Obama, will serve as a liaison between the ports and a task force on supply chain disruptions that was set up in June by President Joe Biden and vice president Kamala Harris.
