Tempers flared on Wednesday when two Mexican senators shoved each other during a plenary session in the country's capital. Alejandro 'Alito' Moreno Cárdenas, national leader of the Institutional Revolutionary Party (PRI) and Gerardo Fernández Noroña, the President of the Senate and member of the Morena party, were seen brawling in footage broadcast by N+. Other legislators had also been involved in the fight in Mexico City. It all began when Moreno approached Noroña to complain that he had not been given the floor after the national anthem was sung in the plenary session to conclude the legislative proceedings.
