The American Israel Public Affairs Committee apologized to President Obama Tuesday for Donald Trump and some attendees cheering the end of his presidency at the group's policy conference.

"While we may have policy differences, we deeply respect the office of the president of the United States and our President Barack Obama," Lillian Pinkus, the newly installed president of AIPAC, said Tuesday, joined by the committee's other lay and professional leaders.

While critiquing Obama' foreign policy initiatives during the conference Monday night, Trump began "With President Obama in his final year ... Yay!" and earned tremendous applause from the 18,000-person crowd at the event in Washington, D.C.

"There are people in our AIPAC family who were deeply hurt last night and for that we are deeply sorry," Pinkus said, her voice choking. "We are deeply disappointed that so many people applauded a sentiment that we neither agree with or condone."

She went on to insist that AIPAC does not "countenance ad hominem attacks" and takes "great offense at those that are levied against the president of the United States of America from our stage."

All primary candidates were invited to speak to the conference in Washington, D.C. Trump spoke along with candidates Ted Cruz, John Kasich and Hillary Clinton. Bernie Sanders was the only major presidential candidate not to attend.
