In announcing this proposal - which did not get more specific than that in terms of what funding mechanisms would be used to finance what kinds of projects - Trump invoked Eisenhower's leadership building the national interstate highway system, saying "the time has come for a new program of national rebuilding."
As he often does, Trump compared the money America has spent in the Middle East with the money that could have been spent on infrastructure at home. He said, "America has spent approximately $6 trillion in the Middle East, all the while our infrastructure at home as crumbled. With that $6 trillion we could have rebuilt our infrastructure twice."
"To launch our national rebuilding," he said, "I will be asking the Congress to approve legislation that produces a $1 trillion investment in the infrastructure of the United States — financed through both public and private capital — creating millions of new jobs. This effort will be guided by two core principles: Buy American, and hire American."
He also mentioned infrastructure at the beginning of his speech, which used similar parallel structure to his Inaugural Address where he first painted a dark picture of what America has become, before defining how things will change under his presidency.
He first said, "We've spent trillions and trillions of dollars overseas while our infrastructure at home has so badly crumbled." He later said, "Crumbling infrastructure will be replaced with new roads, bridges, tunnels, airports, and railways, gleaming across our very, very beautiful land."
Indeed, Trump still talks about infrastructure mostly in terms of transportation infrastructure, though he did mention pipelines such as Keystone XL and Dakota Access at other times in his address.
