Washington (CNN) - As President Barack Obama's Mideast speech this week came under fire from many in the Republican Party for not being supportive enough of Israel, several GOP prospective presidential candidates will be appearing this week at a major event sponsored by a key American Israeli lobbying organization.
Former House Speaker Newt Gingrich, Rep. Michele Bachmann, businessman Herman Cain and former U.S. Ambassador to China Jon Huntsman will attend a policy conference of the American Israeli Public Affairs Committee, Ari Goldberg, a spokesman for the group, confirmed to CNN.
Obama will be making his first appearance as president before an AIPAC event when he addresses the conference Sunday morning. Several leading members of Congress are also scheduled to speak at the event.
AIPAC said this year's conference will be the largest in its history with over 10,000 participants expected to attend.
Gingrich and Bachmann are expected to hold receptions during the event, which begins Sunday, the group said.
Huntsman and Cain are scheduled to attend the group's major dinner Monday night.
Roll Call first reported the attendance of the Republican candidates.
