The White House blocked an Associated Press reporter from an event in the Oval Office on Tuesday after demanding the news agency alter its style on the Gulf of Mexico, which President Trump has bizarrely renamed the Gulf of America.
Before his inauguration on January 20, the president announced plans to change the Gulf of Mexico's name to the "Gulf of America", and signed an executive order as soon as he took office.
The other leading online map provider, Apple Maps, was still using "Gulf of Mexico" in the US earlier on Tuesday, but by early evening had changed to "Gulf of America" on some browsers.
In Britain, Google shows the title "Gulf of Mexico", with the "Gulf of America" in brackets and smaller text underneath.
This week, Google Maps began labelling the sea the "Gulf of America," saying it had a "longstanding practice" of adhering to local naming policies in the countries it operates in.
