Trump Floats 'New America' for New Mexico, Governor Fires Back Fiercely: 'Our Name Predates the United States'

President Donald Trump has sparked a political row after promoting the idea of renaming New Mexico 'New America', prompting the state's governor to deliver a forceful defence of its identity and history.

Trump shared an altered map on social media in which 'Mexico' was crossed out from the state's name and replaced with 'America'. He later described the proposed name as more prestigious and beautiful.

New Mexico Governor Michelle Lujan Grisham rejected the suggestion, declaring that the state's name was not open to debate.

The Democratic governor wrote that New Mexico's name 'isn't up for debate', adding that it had been 'ours since before the United States existed'.

Trump Promotes 'New America' on Social Media

Trump posted the altered map on Truth Social on Sunday, 6 September 2026. The official White House account subsequently shared the image on X, giving the suggestion wider attention.

In a later Truth Social post, Trump said 'many people' had suggested changing the name. He also described New Mexico as 'one of the great vote cheating states of all time', but provided no evidence for that allegation in the post.

The president did not announce an executive order, proposed legislation or another formal process for changing the state's name. The social media posts amounted to a public suggestion rather than an official renaming.

Trump also shared what appeared to be an artificial intelligence-generated video showing him placing an 'America' label over the word 'Mexico' on a road sign welcoming visitors to the state.

Governor Defends New Mexico's History

Lujan Grisham responded through her official X account, arguing that New Mexico's historic identity could not simply be rewritten.

She followed her defence of the state's name by accusing the president of distracting Americans from concerns including fuel prices, grocery costs, healthcare and housing affordability.

Several members of New Mexico's Democratic congressional delegation also rejected the suggestion. Representative Melanie Stansbury responded with 'Oh hell no' and said the state's name carried generations of history, culture and family.

Senators Martin Heinrich and Ben Ray Luján similarly insisted that they would continue calling the state New Mexico.

Does New Mexico's Name Predate the United States?

The governor's historical point is substantially correct. Spanish colonial administration in the region dates to the late 16th century, long before the United States declared independence in 1776.

New Mexico's official historical records list governors serving under the Spanish Crown from 1598.

The region remained under Spanish authority until 1821 and then formed part of Mexico until US occupation began in 1846. The 1848 Treaty of Guadalupe Hidalgo formally established New Mexico as part of the United States.

It was organised as a US territory in 1850. New Mexico was eventually admitted to the Union as the 47th state on 6 January 1912, according to the US Senate's official history.

Its name and regional identity therefore existed for centuries before statehood.

Can Trump Rename New Mexico?

A presidential social media post cannot change the legal name of a state. New Mexico's name is established in its state constitution, and Trump has not presented a formal proposal to alter it.

The episode follows Trump's previous efforts to change geographical names used by the federal government. His administration adopted 'Gulf of America' for the Gulf of Mexico and later promoted 'Lake America' for Lake Ontario.

Those actions involved federal naming policy. Renaming a state would present a fundamentally different constitutional and political question requiring action beyond a presidential declaration.

For now, New Mexico remains New Mexico, and 'New America' has been rejected by the state's current Democratic leadership.
