Two leading Democrats running for statewide office in Pennsylvania will not appear alongside President Joe Biden at a Friday tour of a Pittsburgh-area tech development hub.
Biden will visit Mill 19, a tech hub developed by Carnegie Mellon University on the grounds of a former steel mill, to promote the bipartisan Infrastructure Investment and Jobs Act and discuss manufacturing and supply chains. Joining him will be Democratic Rep. Conor Lamb, who is running to replace retiring Republican Sen. Pat Toomey.
Scientists and engineers working at Mill 19, located in Hazelwood, Pennsylvania, work primarily on robotics and artificial intelligence.
