Trump’s plan to overhaul the nation’s infrastructure, which would allow the government to borrow money from the private sector and use the proceeds to finance new projects, has already been controversial.
But the Trump administration has yet to put out a detailed proposal for how it would pay for it, leaving critics of the plan guessing how it will be funded and what kinds of services the federal government would be able to provide.
The president has yet, however, to release a detailed plan for how he would pay down the debt, which is estimated to run up to $1 trillion.
In his first week in office, Trump has made his first major infrastructure policy decision on Twitter, issuing an executive order directing the construction of the Keystone XL pipeline.
Keystone is one of several pipelines proposed by the Trump team to build new oil pipelines, which are typically a far cry from the Keystone Pipeline, which carries oil from Canada to Texas and New Mexico.
Trump has said he is planning to approve the Keystone project, but not before it is built.
He has also said he would allow construction on other projects that would be funded through tax revenue, but have not released details about what those projects are or how they would be financed.
