The final five presidential candidates will appear on CNN Monday evening as part of a three-hour candidate forum with Anderson Cooper and Wolf Blitzer.
The four candidates will be in town for the pro-Israel AIPAC conference. Sanders told the group he could not attend that conference because of his campaign schedule.
The scheduling comes just days after Fox News decided to cancel its Monday night GOP presidential debate. Donald Trump had pulled out of the debate, citing his AIPAC speech, while Kasich boycotted the event in response to Trump's decision.
