The New Cuba PAC has risen over $350,000 in a span of seven months.

The Washington-based political action committee, which was formed in May 2015, supports federal candidates in favor of lifting the United States' trade embargo on Cuba, according to NBC News.

Ric Herrero, co-director of the New Cuba PAC, said that by ending the embargo "we would be doing a lot more to help empower people and put them in a better position to demand changes from their own government," the news outlet reported.

Among the contributors who donated the maximum $5,000 allowed include health care mogul and top Jeb Bush supporter, Mike Fernandez; former Secretary of Commerce under George W. Bush, Carlos Gutierrez; President of the Miami Heat, Pat Riley, and tech entrepreneur Manny Medina, NBC News listed. The Marriott International hotels group also contributed to the PAC.

Another prominent name, Eduardo Mestre, also donated $5,000 to the group, NBC News further reported. Mestre's father and uncle owned radio stations in pre-revolutionary Cuba and introduced the first major television network on the Caribbean island.

"I think it's worth noting that over half of them are Cuban-Americans. And that shows the seismic shift the community has experienced in recent years," Herrero added, as reported by NBC News.

James Williams, co-director of the New Cuba PAC, said that the group will continue "to support candidates and elected officials" who are working to lift the embargo, a move which they believe will "ultimately benefit both U.S. citizens and the Cuban people," the news outlet continued.

Fernandez, Gutierrez, Medina, and Public Health Trust Chairman and Miami businessman Joe Arriola were among the 10 signatories of an open letter published in December that called the embargo unsuccessful and urged engagement with Cubans on the island, Miami Herald reported.

According to Williams, the success of the PAC's fundraising efforts is "further proof that Americans from across the political and economic spectrum are continuing to unite in their support for normalizing U.S.-Cuba relations," Miami Herald added.

The Hialeah-based U.S.-Cuba Democracy PAC, on the other hand, is also committed to raising funds. The group, which opposes lifting the U.S. embargo on Cuba, aims to promote a transition to a multi-party democracy, the rule of law, and a free-market system on the island, the news outlet listed. The PAC's mid-year 2015 filing with the Federal Election Commission showed $214,322.40 worth of donations.

The U.S.-Cuba Democracy PAC website said that the Castro regime would mainly benefit if the embargo was removed. This condition gives way to Cuba's unconditional transition to democracy, the rule of law, and the free market.
