Florida Gov. Rick Scott (R) announced Wednesday that he is sending back $2.4 billion in federal stimulus money reserved for building a high-speed rail network.

“Rather than investing in a high-risk rail project, we should be focusing on improving our ports, rail and highway infrastructure,” Scott announced, according to the Orlando Sentinel.

Building a transnational network of super-fast trains has been a long-term goal of the Obama administration and a key initiative of its federal stimulus investments. Republicans — and in particular a number of Republican governors — have criticized the plan as another example of ineffective government spending.

Last week Vice President Biden announced a new $53 billion plan over the next six years to build a national high-speed rail network as a means to create jobs and improve American transportation.
