This was also my take-away from a similar article I read earlier. Why not simple ask, "such as?" or, "yes, please remind the voters what you've done for Black Americans."?
Trump does indeed deserve some credit with criminal justice reform. It's arguably the only good thing he did in four years. It's certainly nothing to give any credence to "best since Lincoln".
The First Step Act, which passed with overwhelming support from Republicans and Democrats, takes modest steps to alter the federal criminal justice system and ease very punitive prison sentences at the federal level. It affects only the federal system — which, with about 181,000 imprisoned people, holds a small but significant fraction of the US jail and prison population of 2.1 million.
Essentially, the law allows thousands of people to earn an earlier release from prison and could cut many more prison sentences in the future.
