Michigan Representative Debbie Dingell made a massive dig at Donald Trump and his close aide Natalie Harp over the president’s threat to rename Lake Ontario to the wildly creative “Lake America.”

“Let’s just call it Lake Natalie so we know you’ll start protecting our Great Lakes,” Dingell wrote.

The congresswoman’s comment was a reference to Harp, Trump’s troublingly devoted aide who has drawn scrutiny in recent weeks for her comments to Trump and her closeness to him.

Dingell’s comments come amid Trump’s continued tensions with Canada. In addition to the tariffs he enacted in 2025, Trump announced an additional 50 percent tariff on the nation after a trade negotiation broke down over the weekend.

“The United States is giving serious consideration to changing the name of Lake Ontario to Lake America in that we don’t expect to doing much business with Ontario any longer,” he wrote on Truth Social. “Thank you for your attention to this matter!”

Canadian officials largely shrugged off Trump’s threat.

“We’ll always call it Lake Ontario. Period. We’re proud of our Great Lakes,” Minister of Industry of Canada Mélanie Joly said during a tariff press conference. “We’ll just stand up for what we have … While all these shenanigans are happening, we’ll just be smart, we’ll be strategic, and we’ll fight back.”

Trump made his threat on Tuesday morning after Canada announced retaliatory tariffs against the U.S.

Ottawa announced on Tuesday that it was matching the U.S. tariffs “dollar for dollar,” levying a 50 percent duty on more than 700 U.S. goods.

The most significant of the tariffs is a 50 percent tariff on American steel and aluminum, which doubles the current duty on those products.

The new tariffs are expected to go into effect on September 8.
