On Monday, Mexican President Andres Manuel Lopez Obrador said he delivered a letter to President Biden last week where he pleaded for the US not to prosecute Julian Assange and renewed an offer to grant asylum to the WikiLeaks founder.

Lopez Obrador said he explained in the letter that Assange "did not cause anyone's death, did not violate any human rights and that he exercised his freedom, and that arresting him would mean a permanent affront to freedom of expression."

The Mexican leader said that he previously offered asylum to Assange in a letter to President Trump at the end of his term and again at the beginning of the Biden administration. Last month, Lopez Obrador called Assange "the best journalist of our time."
