New Jersey Gov. Chris Christie's administration is considering investing tens of millions of dollars of New Jersey pension money in a firm whose chairman was among the largest donors to the Christie-run Republican Governors Association. Reuters

New Jersey Gov. Chris Christie still hasn't made a decision on whether he's running for U.S. president in 2016, and no one can force him to choose sooner. The Republican governor said on his monthly "Ask the Governor" radio show that his timeframe for making an announcement won't be changed by anyone. And if he does want to run, even his family can't stop him, according to a tweet from New York Times reporter Michael Barbaro.

"Is it right for me, is it right for my family, is it right for the country -- in that order," he said on the radio, urging his supporters to relax. Christie told listeners he was not collecting money and wouldn't say whether he would soon create a super PAC, the Hill reported.

Christie is seen as one of the top contenders for the 2016 GOP nomination, though he hasn't said anything concrete about the race. Other hopefuls, including 2012 nominee Mitt Romney and former Florida Gov. Jeb Bush, have recently indicated they'll vie for the candidacy, the Associated Press reported.

"What I’ve told everybody, supporters of mine, potential donors of mine, staff, is relax, you know, no one is voting for another 12 and a half months," Christie said Thursday.

Some of Christie's recent comments indicate his bid for the position was likely imminent. International Business Times reported Wednesday that the governor's State of the State speech didn't solely focus on New Jersey. Instead, Christie discussed his visits to other parts of the country, including Maine, Arkansas and notorious swing state Florida. He's been traveling as part of his duties as chairman of the Republican Governors Association.

Christie recently came under fire for attending a Dallas Cowboys playoff game on the dime of team owner Jerry Jones. Critics questioned whether the experience complied with New Jersey's ethics rules.

But Iowa voters indicated this week that they weren't behind a Christie campaign, reported. Among nine potential GOP candidates, he tied for second-to-last place with Rep. Paul Ryan, R-Wisc. Topping the list was Romney.
