Count the ways they’re corrupting DOJ: Presidents don’t direct AG’s to open criminal cases, especially ones designating only Dems for investigation when POTUS himself is involved. DOJ doesn’t publicize criminal investigations & the AG definitely doesn’t assign them on Twitter.

Climate activists often debate whether they should get involved in larger movements for justice, or whether it’s better to just “stay in their lane” of climate.
