Former Colombian president Alvaro Uribe, who is under investigation for alleged witness tampering, resigned his Senate seat on Tuesday.
The Supreme Court placed Uribe, perhaps the South American country’s most divisive politician, under detention in a unanimous decision this month that cited potential for obstruction of justice. He has said he is innocent.
In a letter to the Senate president posted on Twitter, Uribe said the house arrest and what he called violations of legal guarantees impeded him from remaining a lawmaker.
