Alternative for Germany Party Holds Federal Congress

COLOGNE, GERMANY - APRIL 22: Frauke Petry, Chairwoman of the AfD looks on during the federal congress of the right-wing populist Alternative for Germany (AfD) political party on April 22, 2017 in Cologne, Germany. The party is meeting following the recent surprise announcement by its chairwoman Frauke Petry that she will not run in German federal elections scheduled for September. The AfD saw a surge in popularity that helped it capture seats in 10 state parliaments, though more recently that party has seen its poll numbers slip. It has also been plagued by infighting between more moderate and radical factions of its leadership. (Photo by Sascha Schuermann/Getty Images)
