A Mexican Senate session descended into chaos on Wednesday when two senior politicians traded blows following a heated debate over the U.S.'s involvement in the fight against drug cartels.Video captured the explosive momentwhen Alejandro "Alito" Moreno, head of the opposition Institutional Revolutionary Party (PRI), andGerardo Fernndez Noroa, the Senate president of the ruling Morena Party, violently shoved one another after lawmakers finished singing the national anthem to close the days session.The clash erupted after a tense debate, during which the Morena Party and its allies reportedly accused PRI and the conservative National Action Party (PAN) lawmakers of calling for U.S. military intervention in Mexico, a claim the opposing parties reportedly denied.The issue has grown especially contentious following reports that President Donald Trump authorized U.S. military force against Latin American drug cartels designated as terrorist groups.TRUMP APPROVES MILITARY ACTION AGAINST LATIN AMERICAN CARTELS CLASSIFIED AS TERRORIST ORGANIZATIONSMoreno, who said his party was denied the right to speak for closing remarks, was seen approaching Fernndez Noroa, reportedly saying, "Im asking you to let me speak," while clutching the Senate president by the arm."Dont touch me!"
