(CNN) - Texas Gov. Rick Perry will be joined by his family in South Carolina this weekend for a major speech in which he will strongly signal his intention to run for president, two GOP sources told CNN.
Perry is not expected to make a formal campaign announcement on Saturday in Charleston, but people familiar with the planning say that Perry's speech to the RedState Gathering, a convention of conservative activists, will erase any doubt about his presidential ambitions.
During his visit to the key early primary state, Perry will also meet privately with dozens of South Carolina Republican leaders. Perry will then travel to New Hampshire where he will meet with party activists there.
The Texas governor has been meeting with donors and talking to activists in key caucus and primary states for weeks as he lays groundwork for a potential campaign.
A formal declaration of candidacy is expected sometime before Labor Day, but Perry's advisers have not revealed a specific announcement date.
