A wild brawl erupted in the Mexican Senate between two senior politicians following a heated debate over whether US forces should intervene in the country’s fight against drug cartels.

Shocking livestream video captured the explosive moment PRI leader Senator Alejandro Moreno stormed the lectern at the end of Wednesday’s session and grabbed Senate President Gerardo Fernández Noroña of the ruling Morena party as he furiously demanded the floor. 

“I’m asking you to let me speak,” Moreno shouted repeatedly, clutching Fernández Noroña by the arm.  

“Don’t touch me!” Fernández Noroña yelled, as the two pol’s violently shoved each other back and forth, as other lawmakers scrambled to break up the melee.

Moreno pushed his opposing colleague several times, slapped him on the neck, and then knocked another man who tried to intervene to the floor, the chaotic video shows.

Another outraged politician could be seen yanking Fernández Noroña’s suit jacket and swinging at him while the senate leader raced to escape the mayhem. 

The clash came after a tense debate, during which the Morena party and its allies accused PRI and PAN lawmakers of calling for US military intervention in Mexico, a claim the opposing parties denied.

Fernández Noroña told reporters afterwards he would call an emergency session on Friday and propose expelling Moreno, along with three other PRI lawmakers involved in the scuffle.

But Moreno shot back, accusing the senate president of starting the physical altercation.

“Let it be clear: the first physical aggression came from Noroña,” Moreno said in a lengthy X post.

“He threw the first shot, he did it out of cowardice. Morena broke the Chamber’s agreement, and Noroña was exposed in his baseness. What happened is not an isolated incident or an accident: it’s part of Morena’s strategy to impose silence and control.

“That’s how their servile followers act, like Fernández Noroña, with shouts, tricks, and violence.”
