As President Donald Trump intensifies his efforts to hobble the infrastructure that supports Democratic candidates and causes, many liberal advocacy and philanthropic groups say they have moved to protect their organizations, their finances and personnel like never before, according to CNN’s interviews with nearly a dozen officials in the nonprofit sphere. “People are trying to reimagine how to do the work and how to do it safely,” said Jess O’Connell, a longtime Democratic strategist who helps oversee the Democratic Security Project, a nonprofit launched last year that helps organizations harden their operations against risks like physical threats and potential cyber-attacks. It has trained about 8,000 people working in about 1,200 organizations, she said.
