(CNN) - Jeb Bush, Jr. endorsed Jon Huntsman for president Wednesday at a press conference in Miami.
In addition to the formal endorsement, Bush, the son of former Florida Gov. Jeb Bush, said he will become National Chairman of GenH, the former Utah governor's youth and young professionals outreach program.
The grandson of former President George H.W. Bush and nephew of former President George W. Bush said Huntsman is the 2012 candidate "best equipped to defeat President Obama next November."
"In a time of such global upheaval and strife, America needs a serious, experienced leader to restore America's promise, and that leader is Jon Huntsman," Bush wrote on Huntsman's website.
Huntsman met with members of the Bush family earlier this year.
Bush, 28, who backed former New York City Mayor Rudy Giuliani for president in 2008, said the former U.S. ambassador to China is the "only candidate with a proven record of creating jobs, in business and as governor."
Some in the Huntsman campaign hyped an endorsement expected this week, leading some to speculate the announcement would come from the elder Jeb Bush.
Huntsman jumped into the race in June and has since registered in the low single digits in most polls of Republican presidential candidates. But Bush said the figures will change when more Americans become familiar with his record.
"Two years ago, I jumped on board Marco Rubio's campaign when he was polling at 3 percent, and we made history," Bush said referencing the freshman Florida senator. "With Jon, I can't wait to make history again."
