Aug. 28 (UPI) — The leader of the Seneca Nation on Friday called on President Donald Trump to reverse his decision to rename Lake Ontario as Lake America.

Trump on Thursday signed an executive order renaming the body of water amid a trade dispute with Canada.

J. Conrad Sence, president of Seneca Nation, said, “The president cannot assert ownership over our culture or erase it through irresponsible political action.”

“His order should be rescinded and the name Lake Ontario should be left as it is, reflective of the Seneca people, other Haudenosaunee nations and all Indigenous people surrounding the lake,” Seneca said in a statement shared with WIVB.

“To us, Lake Ontario is not a political pawn,” he added. “It does not separate the countries of the United States and Canada. It is all Indigenous land, which has been occupied by Indigenous people since time immemorial.”

Jérôme Marty, executive director at the International Association for Great Lakes Research, said the lake was named by indigenous people.

“They gave the name of Lake Ontario, and then this name was then used to give the name of the province of Ontario, so it’s certainly not the province of Ontario that gave the name of the Lake Ontario, but it’s the opposite,” Marty told WIVB. “It’s prior to Canada, the creation of the United States, it’s been there for a really, really long time.”

Conrad told WGRZ the people of the region will continue to call it Lake Ontario, and urged others to do the same.

In a statement, a White House spokesperson pushed back against the criticism.

“As the president said yesterday, the majority of the great lake’s volume sits in United States territory,” the spokesperson told WIVB. “Thanks to President Trump’s bold action, its name will now reflect its place in America and her heritage.”

Lake Ontario is called sga:nyodai:yoh in the Seneca language, meaning “beautiful lake,” WGRZ reported.

Trump has also changed the name of Alaska’s Mount Denali, an indigenous name, to Mount McKinley after the 25th president of the United States.

He also renamed the Gulf of Mexico to Gulf of America.
