On Wednesday, Senator Alejandro Moreno, of the opposition Institutional Revolutionary Party, grabbed the president of the Senate, Gerardo Fernández Noroña, as he demanded to be allowed to speak.
After some pushing and shoving, Moreno threw punches and a photographer who stepped in to intervene between the leaders was injured.
The altercation followed a heated debate during which the Opposition was accused of calling for US military intervention.
It was not until after the national anthem had been sung that Senator Moreno, angry at not having been allowed to speak during the debate, physically clashed with Fernández Noroña.
The Senate leader said he would call an emergency session to propose expelling Mr Moreno and three other opposition lawmakers who joined in the ruckus.
