New Jersey Gov. Chris Christie is expected to squeeze his way into the already crowded pool of GOP candidates running for the 2016 presidential election.

Sources say that the Republican governor will announce his bid for the White House on Tuesday, June 30, Fox News reports.

According to CNN, a GOP source revealed that Christie will announce his presidential bid at the Livingston High School in New Jersey, which he attended as a student. During his address, he is expected to talk about how his upbringing has helped shaped the person and leader that he is today, said the source.

Later on that day, he is set to travel to New Hampshire to attend a town hall meeting.

Christie would become the fourteenth Republican to enter the race for the party's presidential nomination, following Louisiana Gov. Bobby Jindal who joined on Wednesday.

Other candidates vying for the GOP nomination include Former Florida Gov. Jeb Bush, Florida Sen. Marco Rubio, neurosurgeon Ben Carson and real estate billionaire Donald Trump.

On Thursday, Christie denied speculation that he has come to a decision concerning the 2016 election.

"There's been absolutely no final decision made by me," he said during his radio appearance on NJ101.5 Thursday night. "There's lots of people who speculate lots of things, and I can't be held to account for every bit of speculation that's in the press."

Back in May, Christie called the idea of a pathway to citizenship for the 12 million undocumented immigrants living in the country "extreme." During an interview with Fox News host Megyn Kelly, the governor said that although the U.S. immigration system needs to be reformed, he does not agree with allowing undocumented immigrants to live in the United States permanently.

"I think that's an extreme way to go," said the potential 2016 presidential candidate on "The Kelly File," reports Breitbart.com. "I don't believe that's the way to go and I don't believe that's where the American people are."
