One of the largest labor unions in the country has partnered with a pro-immigration group in a new ad campaign that slams Republican presidential candidates who continue to promote anti-immigrant rhetoric.

Starting on Thursday, the Service Employees International Union (SEIU) and iAmerica Action are releasing a national television advertising campaign that denounces 2016 GOP hopefuls for using "hateful" rhetoric on the campaign trail, reports USA Today.

The six-figure ad buy will run in Spanish on Univision and Telemundo from Thursday to Sunday, and during the Latin Grammy Awards on Thursday night, reports The New York Times. The ads will also air in Nevada, Florida, Colorado and Texas, while the English version of the ad has been uploaded to YouTube.

"We will not accept hate," a voiceover says in the ad. "We will not allow anti-immigrant attacks. We will not support the status quo. Because if they win, we lose."

The ad specifically targets GOP contenders Donald Trump, Florida Sen. Marco Rubio, former Florida Gov. Jeb Bush and Texas Sen. Ted Cruz, who have all promised to end the president's executive orders on immigration if they succeed in winning the White House next year.

"These candidates may be different, but their messages are all the same," the narrator says, after clips of Rubio, Cruz, Bush and Trump are played. "We will not accept hate. We will not allow anti-immigrant attacks."

The ad was released on the anniversary of President Barack Obama's executive actions, which aim to protect up to 5 million undocumented residents from deportation and allow them to work in the country legally. However, Republican leaders have turned to the courts to stop the orders from taking effect.

"We won't forget; in fact, we will remind them that we are more than 30 million eligible Latino and (American Asian Pacific Islanders) voters in 2016," said Rocio Saenz, executive vice president of SEIU International and president of iAmerica Action. "That's not a swing vote, that's a warning."
