(CNN) The liberal advocacy group MoveOn is urging 2020 presidential candidates to skip the American Israel Public Affairs Committee's annual policy conference in Washington next week.

The organization made the call in a news release Wednesday, citing a survey of members who said they believed candidates should not attend the pro-Israel lobbying group's conference.

"We are formally asking 2020 presidential candidates to not attend the conference," Iram Ali, MoveOn's campaign director, told CNN on Wednesday.

The call comes shortly after freshman Rep. Ilhan Omar came under fire for criticism of AIPAC that was perceived to be anti-Semitic. Ali said MoveOn did not consider the Minnesota Democrat's comments or the reaction to them. Instead, concerns such as the partisan nature of AIPAC and the presence of Israeli Prime Minister Benjamin Netanyahu at the conference guided the decision, she said.

"We have four main points as to why we think 2020 candidates should skip the AIPAC conference," Ali said. "First and foremost is that AIPAC has become more and more partisan over the years."
