That is the worst impulses that our party continues," he said.INSIDE ANTIFA-LINKED GROUP'S PLAN TO 'STRUCTURALLY CHANGE' THE US AS MAY DAY UNREST APPROACHESHundreds of groups hosted May Day demonstrations, including chapters of the Democratic Socialists of America, Peoples Forum and Code Pink.A Fox News Digital investigation identified a network of activist groups with roughly $2 billion in combined annual revenue that organized thousands of protests Friday."These kinds of protests are being funded by billionaires against billionaires," Fetterman said.
