Tell them to support the EQUAL Act by the end of the year.
When you call, here’s what you might say: 

“Hello, I am [YOUR NAME], a constituent of Senator [SENATOR’S NAME] from [YOUR TOWN]. As your constituent and a NETWORK Lobby advocate, I am calling to ask that you support including the EQUAL Act by the end of the year. The disparity in the lengths of sentences for crack and powder cocaine crimes has led to an immorally high mass incarceration rate in our country. And, the people that are most severely impacted are Black and Brown people. Families and communities have suffered long enough–now is the time for fair, equitable sentencing reform. Will the Senator support passing the EQUAL Act before the end of the year and affirm that every person is entitled to equal justice under law?”
