Supporters of a Great Lakes cleanup program are taking their case to Congress.
Preliminary budget figures suggest the Trump administration may try to cut nearly all its funding and that contradicts the Trump campaign's pledge last fall to support the program.
The Healing Our Waters-Great Lakes Coalition represents nearly 150 groups favoring the Great Lakes Restoration Initiative.
The program has received about $300 million a year since 2009.
But recently leaked documents say Trump's soon-to-be released budget might request only $10 million.
