White House infrastructure adviser DJ Gribbin told a gathering of the U.S. Conference of Mayors on Thursday that the Trump administration’s upcoming infrastructure proposal will not include any new revenue to pay for $200 billion of new federal spending.

The White House’s proposal, to be released one to two weeks after the Jan. 30 State of the Union address, would be paid for with money from existing transportation programs, Gribbin said, adding that existing formula funding for major programs would not be touched. He later clarified that certain federal transportation money, including for Amtrak and transit programs, would be cut to pay for the program.

“There are reductions, as you know in last year’s budget, when it comes to Amtrak, when it comes to transit, when it comes to a number of programs,” he said. “We will propose repurposing those dollars. What we’re not proposing is, you know, eliminating the Highway Trust Fund or eliminating state revolving funds. So the major delivery mechanisms for funding infrastructure should remain in place. We do want to repurpose some dollars.”

The current funding formula for surface transportation includes money for transit. It’s unclear how the administration would spare the formula funding as it makes other cuts to transit. It could do so by finding cuts to transit spending that falls outside the formula.
