The U.S. Hispanic Chamber of Commerce (USHCC) announced that Republican presidential candidate Jeb Bush will deliver the keynote address at the group's annual convention later this year.

Approximately 7,000 Hispanic business, corporate and community leaders are expected to attend the association's National Convention, which will be held in Houston, Texas, on Sept. 21, said the USHCC in a press release.

"The USHCC has been delighted to work with Governor Bush in the past and are pleased to have him address our members at this year's National Convention," said USHCC President and CEO Javier Palomarez in a statement.

"As an association that represents 3.2 million Hispanic business owners, the USHCC has an accountability to ensure their voices are heard by each candidate -- not only as business leaders, but as tax payers, campaign donors, and ultimately as voters," he added.

The announcement was made on July 13, the same day that three Democratic presidential candidates spoke at the annual gathering of the National Council of La Raza (NCLR), a leading Latino civil rights group, in Kansas City. Although GOP contenders were invited to speak, each one declined the offer.

At the convention, all three 2016 Democratic hopefuls took jabs at the Republican Party and GOP contender Donald Trump over the inflammatory remarks he made last month, calling Mexican immigrants drug traffickers and rapists. 

"It's shameful, and no one should stand for it," said Clinton at the NCLR conference, according to KMBC. "So I have just one word for Mr. Trump. Basta! Enough!"

"For a major candidate of that party to slur a whole people like that is totally unacceptable, period," said Sen. Bernie Sanders.

Meanwhile, former Maryland Gov. Martin O'Malley called Trump a "hate-spewing character" and claimed that "it's so hard to tell him apart from the other [Republican] candidates" when it comes to their views on immigration reform.
