The United States has imposed visa restrictions on Brazilian officials, citing concerns over what they describe as a 'witch-hunt' led by a Brazilian Supreme Court judge. US Secretary of State Marco Rubio accused the judge of fostering a 'persecution, censorship complex,' suggesting the restrictions are a response to perceived abuses of power and suppression of dissent within Brazil's judicial system. The specific officials targeted and the exact nature of the alleged 'witch-hunt' were not immediately disclosed, but the move signals growing tension between the US and Brazil regarding judicial independence and freedom of expression.
