He's right, her husband probably told her she couldn't. I thought that when I saw her
She stated in an interview with TLW w/ Lawrence O'Donnell that she "couldn't keep her composure whenever she saw [her son]" especially when the giant picture of him was behind her. She is articulate, intelligent, and can speak on her own. She debated even coming on stage because of that.
Therefore I ask the question again, would anyone ever say that about a White Christian mother who lost her son and decided not to speak to the entire American public? God forbid.
