Script to read for Representatives who are NOT taking action:
My name is [NAME], I am calling as a constituent of [YOUR REPRESENTATIVE NAME] to call upon them to add their name as a co-sponsor to the House Joint Resolution to block the sale of $735 million in U.S. weaponry to the Israeli government. Under no circumstances should we be approving weapons sales to the Israeli government as we see them deploy military resources to target Palestinian families, media outlets, schools, hospitals, and Gaza’s only COVID test site. I am asking my Representative to add their name to the Resolution. Thank you.
