Story highlights Clinton, who lost the 2016 election to Trump, is launching a PAC

Clinton, according to the sources, is currently working with former aides and donors to build an organization that will look to fund and invest in groups that have impressed her since her 2016 election loss.

Clinton identified herself as part of the so-called resistance earlier this week, and that was not in passing. The former secretary of state has been watching groups stand up to Trump from afar and is "particularly fired up," in the words of one source, to fund these groups and broaden their reach.
