(CNN) - Republican Gov. Chris Christie of New Jersey will announce he will not run for president in 2012, a GOP source in New Jersey told CNN Chief National Correspondent John King.
The first-term governor, who has considered launching a bid for the Republican presidential nomination, will make the announcement at a news conference in Trenton on Tuesday at 1 p.m. ET. A handful of operatives and friends who made clear they were ready to help his bid told King they received no call to arms ahead of Tuesday's announcement.
After repeatedly shooting down rumors he would throw his hat in the ring, Christie spent time recently discussing the possibility with his family, friends and operatives. One source told CNN Christie discussed the pros and cons of a late entry into the race with his wife.
But another source told CNN Chief Political Analyst Gloria Borger that Team Christie was making the decision in a methodical way, addressing whether he is ready to be president and if, given the campaign calendar, there is time to make the leap into areas like national security with which he has little to no familiarity.
Another Republican strategist familiar with Christie's thinking said he was "very moved" by the appeals he heard last week at the Reagan Presidential Library, including from former first lady Nancy Reagan and former Secretary of State Henry Kissinger at a meeting Christie had recently with top GOP donors.
Christie spoke at the library in Simi Valley, California last week at the request of Mrs. Reagan.
According to the same source, who was briefed on the meeting, Kissinger made the point that he has worked with seven presidents and what matters is character and judgment. Christie has both, Kissinger told the group.
The ongoing coverage coincided with the release of new poll results that showed Christie in forth place nationally among the other GOP White House contenders. Christie received 10% support among registered voters behind former Massachusetts Gov. Mitt Romney's 21% and former Godfather Pizza CEO Herman Cain and Perry's 14%, according to the ABC News/Washington Post poll released Tuesday.
Forty-two percent of those surveyed said Christie should run for the nomination, 34% said he should not and 24% were unsure.
The Washington Post/ABC News poll surveyed 1,002 adults by telephone from September 29-October 2. The sampling error was plus or minus four percentage points.
