Donald Trump’s administration is planning to withhold some public health and transportation money from a group of Democratic-led states.

Full details have not been released, including whether the states could take any steps to avoid losing the funding. The federal government cited concerns over fraud and mismanagement of taxpayer dollars, but has not presented evidence beyond remarks from Trump and others in his administration.

The approach has become a familiar one for the administration, and this time focuses on frequent targets: California, Colorado, Illinois and Minnesota.

Courts have so far temporarily blocked other similar efforts by this administration to restrict funds.
