Rep. Debbie Dingell turned President Donald Trump's proposal to rename Lake Ontario "Lake America" into a pointed attack involving White House aide Natalie Harp, injecting an increasingly personal controversy surrounding Trump's executive assistant into an already tense U.S.-Canada dispute.
The Michigan Democrat responded after Trump said the U.S. was giving "serious consideration" to changing the name of Lake Ontario, one of the five Great Lakes and a body of water shared by the U.S. and Canada. Dingell suggested an alternative designed to mock both Trump's proposal and his relationship with one of his closest aides.
"Let's just call it Lake Natalie so we know you'll start protecting our Great Lakes," Dingell wrote on X, referring to Harp.
Trump's proposal follows his earlier effort to rename the Gulf of Mexico the "Gulf of America." But Lake Ontario presents a different diplomatic complication because an international boundary runs through the lake and Canada shares jurisdiction over its waters.
Canadian officials have rejected Trump's proposal. Ontario Premier Doug Ford has said the body of water will continue to be called Lake Ontario in Canada, underscoring the practical limits of Washington's ability to impose a new name beyond the U.S. side.
The dispute comes amid worsening relations between Washington and Ottawa over tariffs and trade. The two countries have exchanged increasingly sharp rhetoric as U.S. trade measures and Canadian retaliation strain one of the world's largest bilateral economic relationships.
Dingell's response shifted attention from the geopolitical symbolism of "Lake America" to Harp, whose unusually close access to Trump has become a recurring subject of political attacks and media coverage.
Harp serves as Trump's executive assistant and frequently accompanies the president. She has been nicknamed Trump's "human printer" because of her practice of supplying him with printed news articles, social-media posts and other information.
Her prominence has increasingly attracted attacks from Democrats. Sen. Jon Ossoff of Georgia recently mocked Trump over Harp traveling with him, prompting Republican Sen. Bernie Moreno to characterize some of the criticism surrounding her as "super misogynistic."
Eric Trump has also defended Harp amid the scrutiny, calling her a "genuinely good person" and describing attacks against her as "absolute trash."
Harp's association with Trump dates to before her White House employment. In 2019, while being treated for bone cancer, she publicly credited Trump's Right to Try law with helping her obtain access to experimental treatment. She subsequently became involved in Trump's political operation before eventually becoming his executive assistant.
Attention surrounding that relationship intensified after reporting about letters Harp wrote expressing strong personal admiration for Trump. In one, she described him as her "guardian and protector."
Harp's brother, Preston Harp, added to the scrutiny during a CNN interview this month when he described his sister's devotion to Trump as an "unhealthy obsession."
His remarks followed CNN reporting about a 2023 episode in which Natalie Harp allegedly sought to accompany Trump to a court appearance despite initially being told there wasn't room for her in the motorcade. According to the report, she ultimately traveled in the trunk area of one of the vehicles.
Preston Harp cited the episode while discussing his concerns, though his description of his sister's relationship with Trump represented his personal assessment rather than an established finding about her motives.
