(CNN) Editor's note: This story, originally published on October 1, has been updated to reflect Bernie Sanders will not appear at the event. Sanders has canceled events related to his 2020 presidential campaign as he recovers from a heart attack.

Sanders had accepted an invitation from the Human Rights Campaign Foundation to appear at the event, but has canceled events related to his 2020 presidential campaign last week after a heart attack in Nevada. His campaign told CNN that the senator will still participate at its primary debate on October 15 in Westerville, Ohio.

The October 10 event in Los Angeles will air from 7:30 p.m. to 12 a.m. ET and feature Democratic presidential candidates appearing back-to-back throughout the evening and taking questions from audience members and a CNN moderator.

The town hall, which HRC bills as the "Power of our Pride," will air exclusively on the CNN television and digital platforms and coincides with the 31st anniversary of National Coming Out Day on October 11.
