Dr. Yehuda David pulled out of the Habayit Hayehudi primary on Sunday, because he has cancer.
David is known for refuting claims that 12-year-old Muhammad al-Dura was killed by IDF gunfire. David was acquitted of libel charges in February for saying al-Dura's father, Jamal al-Dura sustained an injury in his hand in an earlier incident and not in 2000, when his son died.
"I'm sorry to say that I am leaving the race because of cancer, which was discovered months ago. I am unable to fight both of these battles," David told Galei Yisrael Radio.
The doctor said he fainted on Thursday and feels he needs to strengthen himself and his family.
Habayit Hayehudi members will elect the party's list for the next Knesset on Tuesday.
