President Donald Trump declared on Saturday that the official language of the United States will be English, noting that the language is pivotal to the history and modern culture of the nation.

The executive order from Trump said that “a nationally designated language is at the core of a unified and cohesive society, and the United States is strengthened by a citizenry that can freely exchange ideas in one shared language,” an assertion he believes ought to be federal policy.

The action will therefore empower federal agency heads to provide government services in a way that serves the public while promoting English, although they will not be required to “amend, remove, or otherwise stop production of documents” in languages other than English.

“In welcoming new Americans, a policy of encouraging the learning and adoption of our national language will make the United States a shared home and empower new citizens to achieve the American dream,” the order described. “This order recognizes and celebrates the long tradition of multilingual American citizens who have learned English and passed it to their children.”

The order revoked another action signed by President Bill Clinton in 2000 which required federal agencies to examine services and improve them for people with limited proficiency in English.

Trump argued during the primary race in 2016 that the United States should establish English as the official language, observing that English is necessary for assimilation and criticizing former Florida Republican Governor Jeb Bush for speaking Spanish on the campaign trail.
