The following excerpt is from an Elizabeth Warren fundraising letter. Don't know how to post a link to it. How are we able to influence legislation this way? I hope we can do more of it.

With public attention, we changed a terrible provision in this bill that would have allowed Donald Trump to have complete control over how the opioid money would be spent. If Trump had wanted to punish states with terrible opioid epidemics that didn’t vote for him – like Massachusetts and New Hampshire – he could have denied us what little opioid crisis funding was in this bill. Thanks to your help, all states should now receive their fair share. That makes a real difference.
