http://www.slate.com/blogs/the_slat...curring_donations.html?wpsrc=sh_all_dt_tw_top On Thursday, Mic confirmed that, no, there is no button to undo your recurring payment to the Trump campaign. You can’t delete the recurring payment. You can’t even delete your credit card information (you can update it, but it has to be with a different valid card number). So you just keep paying Trump’s campaign, we suppose, until the end of time. Clinton’s campaign has a “remove card” option on its site for recurring payments, Micreports. Trump's campaign did not return multiple requests for comment to the site.
