From Feiglin’s Facebook Page:

Moshe Feiglin: Today, Ta’anit Esther, I understood that we have reached the red line for Jonathan Pollard. If we cross it, G-d forbid, we will lose him. The President of the United State, Barack Hussein Obama, is scheduled to visit Israel and to speak in the Knesset on Erev Pesach. You are welcome, Mr. President – with our brother, Jonathan. With G-d’s help, when Obama releases our brother, Jonathan, I will be pleased to honor him and to listen to his speech in the Knesset. If G-d forbid, he will not release our brother, I call upon all my colleagues, the Knesset Members, to join me and to leave the Knesset plenum empty during the speech of the head of state who has been holding our brother Jonathan captive for 28 years.
