Donald Trump is on track to make history by signing an executive order that would designate English as the official language of the United States, according to multiple White House sources.

While English is already the most widely spoken language in the country, the U.S. has never formally declared an official language at the federal level in its nearly 250-year history.

However, every major national document, including the Constitution and the Declaration of Independence, has been written in English.

During his campaign last year, Trump criticized the increasing presence of other languages in the U.S., stating at the Conservative Political Action Conference:

“We have languages coming into our country.

“These are languages – it’s the craziest thing – they have languages that nobody in this country has ever heard of. It’s a very horrible thing.”
