(CNN) - New Jersey Gov. Chris Christie won't be able to meet with Rand Paul when the Kentucky senator travels to the Garden State next week.
Christie said he has a short trip planned with his wife for her 50th birthday.
"In a choice between Mary Pat Christie and Rand Paul, it's no choice for me," Christie said Tuesday at a press conference in Newark. "So I'll be with Mary Pat."
Paul and Christie engaged in a high profile, intraparty feud this summer over their differences on federal surveillance programs and government spending. Paul, seeking to draw a cease-fire, offered to have a beer with Christie, but the outspoken governor said he was too busy to go down to Washington as he's campaigning for re-election in New Jersey this year.
Paul's campaign recently reached out to Christie's aides to try and arrange a meeting when Paul campaigns on Friday, September 13 for Steve Lonegan, the Republican nominee in New Jersey's special Senate election, a Paul political adviser told CNN.
But Christie said he and his wife are leaving that same Friday and will come back Sunday, on her birthday.
"I am taking her away, just the two of us," he said.
Both Republicans are considered potential contenders for the 2016 GOP presidential nomination. Their recent back-and-forth spurred a larger debate about the party's divide between establishment Republicans and a more libertarian-leaning wing.
While Christie endorsed Lonegan in person shortly after the businessman became the Republican nominee last month, Christie has largely kept his distance from the candidate, who's known as a staunch conservative.
Lonegan, however, trails behind Democratic nominee and Newark Mayor Cory Booker in recent polls. The winner of October's special election will finish the term of the late Democratic Sen. Frank Lautenberg, who died earlier this year.
Word of Paul's trip to New Jersey to campaign with Lonegan was first reported by Politico.
