France, Germany, the European Union and the United Kingdom are hitting out at a U.S. decision to impose travel bans on five Europeans the Trump administration accuses of pressuring tech firms to censor or suppress American views. The EU’s executive branch, the European Commission, which supervises tech regulation in Europe, is warning that it will take action against any “unjustified measures." U.S. Secretary of State Marco Rubio called the five "radical" activists. They include Thierry Breton, who is the former EU commissioner responsible for supervising social media rules. The move is part of a Trump administration campaign against foreign influence over online speech.
