Rep. Debbie Dingell, D-Mich. declared that she will introduce legislation targeting President Donald Trump's executive order to rename Lake Ontario as Lake America.

"The Great Lakes are a shared treasure that generations of Americans and Canadians have worked together to protect. That’s why I'm introducing legislation to keep Lake Ontario as Lake Ontario and block President Trump’s idiotic order," Dingell declared in a Thursday post on X.

The president's executive order called for updating "the Geographic Names Information System (GNIS) to reflect the renaming of the Lake and remove all references to Lake Ontario from the GNIS, consistent with applicable law."

The order also stated that, "The Board on Geographic Names shall provide guidance to ensure all Federal Government references to Lake Ontario, including on executive department and agency maps, contracts, and other documents and communications, shall reflect its renaming."

TRUMP RENAMES LAKE ONTARIO 'LAKE AMERICA' AMID INTENSIFYING US-CANADA TRADE DISPUTE

Trump posted to Truth Social on Thursday what appeared to be the content of a message from U.S. Geological Survey Director Dr. Ned Mamula.

"As of 4:30 pm today the U.S. Geological Survey has officially designated the former Lake Ontario to be renamed as Lake America in all official USGS electronic documents," Mamula noted. "The change will begin occurring in printed documents over the next several days. This change has also been made official in the Geographic Names Information System."

Dingell's post on X linked to a Politico report, which stated that Dingell noted in an interview that she plans to introduce a measure on Monday to nullify Trump's move to change the lake's name.

Canadian Prime Minister Mark Carney declared in a Thursday post on X, "The name Lake Ontario comes from the Wendat word Ontari’io, which, appropriately, means 'the lake is beautiful, the lake is big'. The name is more than 400 years old, predating both the Confederation of Canada and the Declaration of Independence of the United States of America.

"We know that America is changing. Their trading relationships, their foreign policies, their national monuments, their hydronyms. Canadians also know that naming reality means calling it Lake Ontario – then, now and always," Carney said in the post.
