Independent congressional investigators are raising questions about why New Jersey Gov. Chris Christie scrapped the Hudson River rail tunnel project in 2010.
Christie had said he feared cost overruns when he canceled what was then the largest public works project in the nation.
But a Government Accountability Office report, obtained by The New York Times, finds cost estimates for the tunnel had remained unchanged and state transportation officials had said the project would cost less than Christie had estimated.
The GAO also concluded Christie had misstated New Jersey's share of the costs.
Christie spokesman Michael Drewniak told the newspaper the report failed to consider other expenses associated with the tunnel and the fluctuating estimates suggest no one really knew how much the project would cost.
