California Gov. Gavin Newsom’s office said the governor was denied entry into a venue at the World Economic Forum in Davos, Switzerland, on Jan. 21, after being invited to speak at the event due to “pressure” from the Trump administration.

Newsom had been scheduled to speak with Fortune at the USA House, Davos, a privately organized event, at the World Economic Forum, which has been recognized by the U.S. government as the nation’s headquarters in Davos.
