Former Mexican president Vicente Fox tweeted a selfie of himself smiling in Cancun, telling GOP frontrunner Donald Trump “YOU ARE NOT WELCOME HERE” in his latest rage against the billionaire and his plan to halt uncontrolled illegal immigration from Mexico.

The viral tweet topped off a fresh Fox Twitter rant the former president typed in English.

Pathetic,Trump suffers from, disruptive narcissist personality. Which means,the belive that he is special and unique. — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Trumps narcisism means he needs,excessive an permanent admiration. Personal behavior to explote others. Lack of empathy. He loves t provoke — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

What we can expect from Trump, excessive shameless self promotion. If it works is HIM, if it fails is others. — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Trump is not sane to excersice power.He said "I am sorry losers and haters,but my intelectual coeficient is one of the highest -you now it- — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Trump has profound, insulting arrogance, he demands treatment of a king or dictator. Where is that great nation going? And the Republican? — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Fox appears to have rescinded his ignored offer to “come visit” Mexico after Trump proposed to tax remittances flowing into Mexico from illegal aliens working off the books or using stolen Americans’ identities in the United States. On Wednesday, he balked at the very idea of taxation (indeed, Fox did deliver a speech at a libertarian conference in 2015).

How is it possible Trump's nonsense proposal to steal, take away money earned through decent work? — Vicente Fox Quesada (@VicenteFoxQue) April 6, 2016

Trump is absolutely crazy and ignorant.poor Republican party.poor US, — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

If Trump thinks US will survive enclosed in 4 walls. The consequences is depression, unemployment, desperation, a isolation. — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Trump is a looser, in business and in campaigning. He will never make it. He only is increasing hate ,violence. How can people stand him? — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Trump,do you have any idea, what is the amount of remittances coming to US from abroad. Remember to Every action fallows a reaction. — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

A war with Mexico is a lost proposition. What is happening with you. Why so much hate? What we done to you? Come and visit us! — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Trump don't destroy,what we have built with so much effort. Do not destroy US world leadership. — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Trump, stop fighting with everybody.

Stop destroying world relations.

Document yourself,get information go back to school. — Vicente Fox Quesada (@VicenteFoxQue) April 7, 2016

Fox has denounced Trump repeatedly for say as president he’d build a wall on a dangerous and unsecured southern border. He recently taped a mock debate with Trump, again blasting Trump’s proposed wall, and wrote up his statements in a Guardian op-ed while calling Trump a “dictator.”

Trump’s senior policy adviser Stephen Miller responded to criticism of Trump’s immigration plans on Thursday:

“Several decades of open-borders policies with Mexico have primarily helped two groups in Mexico: drug cartels that are terrorizing the country and corrupt politicians that have refused to implement social reforms, political reforms, economic reforms,” he told CNN’s Wolf Blitzer. “If we continue the same policy of illegal immigration, Mexico is going to stay poor forever.”
