(JNS) - An unusual duo made the two-mile-plus walk from Auschwitz to Birkenau last week during the annual March of the Living in Poland: Robert Kraft, Jewish billionaire New England Patriots owner and philanthropist who launched a campaign last month opposing antisemitism, and Meek Mill, a prominent rapper.

"It's important for me to learn humanity's history," said Mill.

"It's also important for me to support Robert, all my Jewish friends, everyone that always supported me," he added.

Mill credited Kraft with learning about his culture and background, as well as supporting him "at a very high level" when he was jailed on gun and drug charges at age 19.

"He's a man who's very caring, and it's very important to him to build bridges between people of the Jewish faith and people of color in America," said Kraft about Mill.

"I always stand on anything that condemns racism," Mill told CNN. "Now that I had an education, I'll definitely spread the word to people in my culture about what I've seen and what I felt at that concentration camp."

As for Kraft, he has just teamed up with Brandeis University and the Foundation to Combat Antisemitism to launch a campaign against antisemitism, marked by ads with a blue square emoji. The $25 million initiative to battle Jew-hatred was launched in late March.
