AFL-CIO President Richard Trumka rose to power in combination with President Obama. Trumka became president of the AFL-CIO at the same time President Obama took office in January 2009.
The Chicago machine organized a pact between the revolutionary communists (RevCom) and labor unions in 2007; specifically to assist the installation of Obama in the 2008 presidential election. The AFL-CIO (Nicholas), SEIU (Andy Stern), UFCW, UAW and AFSCME labor unions all agreed to assemble their foot-soldiers in common cause. That union army defeated Hillary Clinton in a brutal 2008 presidential primary. The communists won. The rest is history.
