A state-federal project to prevent invasive carp from reaching the Great Lakes had been halted by the Trump administration. The Army Corps stopped work on the Brandon Road Interbasin Project without explanation in July. This pause left officials in two states searching for answers, as environmental officials found invasive carp near Lake Michigan.

Michigan Gov. Gretchen Whitmer made a call to President Donald Trump, which was followed by the lifting of the hold on the project. The phone call was a notable intervention by the Democratic governor.

Further details about the project and the call are available from the source.
