On Friday, in response to President-elect Donald Trump’s tweets about how Mexico will reimburse America for the Great Wall, the former President of Mexico took to Twitter to hit back at the incoming POTUS.

This isn’t the first time Vicente Fox has gone after Trump over the issue of Trump’s proposed border wall along the Mexican border.

Fox followed that tweet up by trolling Trump on the intelligence report that was released today that showed Russia meddled in the election to help Trump. He also brought up Trump’s popular election loss to Hillary Clinton.

The president-elect tweeted about the issue of Mexico reimbursing the United States for the wall due to reports that he’s going to ask Congress to fund the wall in the upcoming spending bill.

This isn’t the first time Vicent Fox has used an f-bomb in refuting Trump’s claim that Mexico would pay for a border wall. Last February, he told Fusion’s Jorge Ramos that “I’m not going to pay for that f*cking wall!”
