Cont. (ran out of space in the last comment)
I called Rick Scott's office urging him to join the bipartisan governors of Colorado, Connecticut, Delaware, Maryland, Massachusetts, Minnesota, Nevada, New Hampshire, New Jersey, New York, North Carolina, Oregon, Pennsylvania, Rhode Island, and Virginia, to block Florida state resources from being used to separate immigrant children from their parents.
I called Pam Bondi's office asking why she didn't join the AGs from California, Connecticut, Delaware, DC, Hawaii, Illinois, Iowa, Maine, Maryland, Massachusetts, Minnesota, New Jersey, New Mexico, New York, North Carolina, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia and Washington, who signed a letter to Jeff Sessions and Kirstjen Nielson calling for an immediate end to family separation and an end to the "zero tolerance" policy. (Those AGs are all Dems, but I pointed out the letter signed by the 13 GOP senators.)
I called HHS to complain when Nelson was turned away from inspecting the camp in Homestead after he and Rep. Debbie Wasserman Schultz had been given assurances by the contractor that they would be admitted. I quoted Nelson, who said, "I have a responsibility as oversight of your agency. We appropriate the monies that run your agency in that capacity we want to know that you're doing your job right. And at the same time we have concern for the welfare and the caring of these children and we want to see it."
I also signed numerous petitions, tweeted like crazy, and shared info on social media. I emailed 23andMe, adding my voice to those of other customers and Rep. Jackie Speier, who asked that the company use DNA testing to help reunite children with their families (https://www.buzzfeed.com/lissandravilla/a-congresswoman-is-asking-23andme-to-help-reunite-kids-and).
I'll be participating in an action on June 30, one of now more than 400 protests planned across the country: https://act.moveon.org/event/families-belong-together/search/?.
