Former staffer for President Clinton Jamie Metzl is urging Democrats to confront what he describes as the “dangerous” far-left faction within their own party. “They're inciting violence against American citizens on the street … they are openly supporting US-designated terrorist organisations like Hamas and Hezbollah and the Muslim Brotherhood. “If we can't speak up against the dangerous far left in our own party, what kind of credibility will we have calling on Republicans to stand up against the dangerous far right of theirs? “This is not a Democratic issue; it's not a Republican issue, but standing up for America's Constitution and our democracy is an American issue.”
