U.S. President Donald Trump’s plan to require tourists to hand over their social media data ahead of next year’s World Cup generated outrage on Wednesday. 

An elected European official, human rights groups and fan organizations condemned the move and urged the world football governing body, FIFA, to pressure the Trump administration to reverse course.  

Visitors to the U.S. — including those from visa-free countries such as France, Germany and Britain — would have to submit five years of social media activity before being allowed through the border, according to a proposal by the Trump administration published Wednesday. 

The new rules, which would also require travelers to provide emails, phone numbers and addresses used in the last five years, would come into effect early next year — shortly before hundreds of thousands of football fans are expected to travel to the U.S. to watch their teams compete in the World Cup, which begins in June. The U.S. is co-hosting the tournament with Mexico and Canada. 

“President Trump’s plan to screen visitors to the U.S. based on their past five-year social media history is outrageous,” Irish Member of the European Parliament Barry Andrews of the centrist Renew group said in a statement.  

“Even the worst authoritarian states in the world do not have such an official policy,” he added. “The plans would of course seriously damage the U.S. tourist industry as millions of Europeans would no longer feel safe … including football fans due to attend next year’s World Cup.” 

The Trump administration has stepped up social media surveillance at the border, vetting profiles and denying tourists entry or revoking visas over political posts, prompting rights groups to make accusations of censorship and overreach. 

Minky Worden, director of global initiatives at Human Rights Watch — which has repeatedly warned FIFA about its interactions with the Trump administration — called the new entry requirements “an outrageous demand that violates fundamental free speech and free expression rights.” 

“This policy expressly violates [football governing body] FIFA’s human rights policies, and FIFA needs to pressure the Trump administration to reverse it immediately,” she added. “The World Cup is not an opportunity for the U.S. to exclude and harass fans and journalists whose opinions Trump officials don’t like.” 

FIFA directed POLITICO to the U.S. State Department when asked for comment. The State Department and Customs and Border Patrol, the agency that authored the proposal, did not immediately respond to POLITICO’s requests for comment.  

The prospect of turning over years of social media data to American authorities also sparked fury from football supporters, who turned their fire on FIFA. 

“Freedom of expression and the right to privacy are universal human rights. No football fan surrenders those rights just because they cross a border,” said Ronan Evain, executive director at Football Supporters Europe, a representative group for fans. “This policy introduces a chilling atmosphere of surveillance that directly contradicts the welcoming, open spirit the World Cup is meant to embody, and it must be withdrawn immediately.

“This is a World Cup without rules. Or at least the rules change every day. It’s urgent that FIFA clarifies the security doctrine of the tournament, so that supporters can make an informed decision whether to travel or stay home,” he added.
