California sued Tuesday to block federal officials from canceling $929 million for the state's high-speed rail project, escalating the state's feud with the Trump administration.
The Federal Railroad Administration announced last week it would not give California the money awarded by Congress nearly a decade ago, arguing that the state has not made enough progress on the project.
The state must complete construction on a segment of track in the Central Valley by the end of 2022 to keep the money, and the administration has argued the state cannot meet that deadline.
But Lenny Mendonca, chairman of the California High-Speed Rail Authority, said in a statement that California has performed its obligations on the project thus far.
"While this project has long been a political football, our determination to get the work done and bring high-speed rail to California is undaunted," he said.
