Óscar Arias Sánchez, the former president of Costa Rica who was awarded the Nobel Peace Prize in 1987, has had his visa revoked without explanation this week.
The New York Times reported that Sánchez has been a "vocal critic" of President Donald Trump and that the rescission of his visa "appears to be the most high profile in a string of individuals who have had their visas canceled or been denied entry as the Trump administration bars people who it says have 'hostile attitudes' toward the United States."
During a news conference in Costa Rica on Tuesday, Sánchez said he didn't know why his visa had been revoked, but he vowed not to remain silent in his criticism of Trump.
“If someone wants to punish me in the hopes of silencing me, that isn’t going to work,” he declared.

As the Times notes, Sánchez earlier this year criticized Trump for trying to boss around neighboring nations and compared him to a "Roman emperor, telling the rest of the world what to do."
Sánchez won the Nobel Peace Prize for his work in crafting a plan to end civil wars across Central America.
