From Bloomberg Politics:

Republican presidential hopeful Jeb Bush made an unannounced stop in Krakow on Wednesday to tour the Auschwitz concentration camp in Poland.

Bush toured the camp with wife, Columba, Bloomberg confirmed. He didn't invite the roughly 10 reporters from the U.S. and Europe following the former Florida governor on his five-day, three-country tour, out of respect for the site and those affected, a Bush aide said.

More than 1 million people, mostly Jewish prisoners, died at the camp during World War II.
