President Joe Biden on Tuesday spoke with the chief executives of Walmart WMT, +0.35%, UPS UPS, +0.32%, FedEx FDX, +0.38% and Target TGT, +0.72% on Tuesday to discuss steps the administration and private sector can take to "further strengthen our supply chains and build on steps we've already taken to speed up deliveries and lower prices," the White House said. The conversations followed the White House's unveiling of a plan Tuesday morning containing what it called "a set of concrete steps to accelerate investment in our ports, waterways, and freight networks." The bipartisan infrastructure bill passed by Congress contains $17 billion for such facilities, and Biden will talk up his plan for ports during a visit Wednesday to Baltimore.
