That interview is at the 7:05 mark in this lengthy segment on CNN gun control.
I also found something else very interesting on Samantha Grady. She added someone to the Troupe 4879 -Mobilizing MSD Club Facebook page on February 21, 2018. This means that she is involved with the drama club at the school also.
Here's that image and link:

Thus, it looks like in order to make it into the mainstream media's antigun campaign the job requirement is 1) be a member of the schools drama club, 2) have prior acting, reporting or filming experience and 3) attend holocaust class.
Regular students who just do history and other subjects need not apply.
The person she added to the Drama Group is Steve Corin who is the brother of another media rolled out student Jaclyn Corin.
This is Jaclyn Corin on the Ellen Degeneres Show on February 23rd. She is on the left.
If they are on the Ellen show, do you need any more evidence that things are not what they seem?
