Christian Democrats (CDU) Hold Annual Federal Congress

Horst Seehofer, Head of Bavarian Christian Democrats (CSU) and Governeur of Bavaria walks behind the German Chancellor and Chairwoman of the German Christian Democrats (CDU) Angela Merkel and the prime minister of Hesse Volker Bouffier to speak at the annual CDU federal congress on December 15, 2015 in Karlsruhe, Germany. The CDU is meeting following a dramatic year in which Germany admitted approximately one million migrants and refugees under an open-door policy spearheaded by Merkel. A growing number of CDU members think Merkel has gone too far and see the influx as a burdensome challenge that should have been capped sooner.
