Former Costa Rican President Óscar Arias Sánchez, who likened President Trump to "Roman emperor" earlier this year, says he fears the U.S. revoked his visa over criticisms of Trump.

Arias, 84, told the AP on Wednesday that he received an email from the U.S. State Department on Tuesday, notifying him of the decision.

The State Department revoked the visa of former Costa Rican President Oscar Arias on Tuesday. Arias is a Nobel Peace Prize winner who often traveled to the United States to receive further accolades for his work while he was president.
