(CNN) - Bill Clinton will join Barack Obama and John McCain in visiting Ground Zero this Thursday in memory of the victims of September 11, and deliver a speech focused on national security threats.
“But just as we reflect on the past, we must look ahead to ensure we are doing all we can to support families, unite our communities, and protect our country from future acts of terrorism," said the former president in a statement released by his office.
The McCain and Obama campaigns released a joint statement over the weekend announcing that both men will appear together in New York to mark the seventh anniversary of the attacks. The campaigns have also pledged to abstain from all negative campaign ads on that day.
Also Thursday, Bill Clinton and Barack Obama will meet at the former president's Harlem offices - their first extended in-person encounter since the tense primary season.
(UPDATED to clarify McCain and Obama are visiting Ground Zero Thursday, but will not be at the memorial ceremony.)
