The former House speaker outlined his plans on a conference call Wednesday with former aides, according to people who were on the call.
The participants declined to be identified because they were not authorized to speak for Gingrich.
Gingrich said he has not made a final decision on whether he will seek the White House, but said he is clearly leaning toward running.
At an appearance last week in Atlanta, Gingrich said he's exploring a presidential bid but stopped short of forming an exploratory committee.
He conceded Wednesday that the announcement was mishandled and said he expects to open a campaign office soon in his old home state of Georgia.
