The Apprentice boss has been under fire from the Latino community ever since he launched his bid for the White House in June (15), and suggested many Mexican immigrants to the U.S. were "rapists" who brought crime and drugs to America.

On Tuesday, Trump hit headlines again for tossing respected journalist Jorge Ramos out from a campaign press event in Iowa after the newsman refused to sit down after asking the politician to explain the details of his immigration reform plans.

The Livin' La Vida Loca star penned a rant against Trump on Twitter.com on Wednesday (26Aug15), writing, "Enough is enough... We cannot allow this behavior. We have to defeat the power that Trump pretends to have over Latinos, anchored in low rhetoric and xenophobic speech, which his campaign team is convinced works for him."

Now, Wisin has joined Martin by speaking out against the presidential hopeful in a new letter, in which he writes: "No one who aspires to lead a country can have the audacity to violate inherent human rights, like equality of races and freedom of speech.

"The arrogance shown against Jorge Ramos reflects on a man who didn’t learn from the history that so hurt the United States and caused so much suffering due to inequality among races. Men like Martin Luther King were able to dignify human beings without discriminating. Us Latinos are able to achieve the impossible!!! Together we are invincible!!! ENOUGH!!

"I join the voice of my friend and compatriot, Ricky Martin, and that of millions of Latinos who have grown up, studied and work day to day in this country. I invite all our community to come together and together raise a single voice: ENOUGH! Mr. Donald Trump; someone who disrespects one of us disrespects all of us."
