Ed Sheeran asked Patriots owner Robert Kraft for $2 million aid donation after Macklemore was dropped from his tour for pro-Palestine comments

New England Patriots owner Robert Kraft shot back at Macklemore after he challenged him to match a $1 million donation he is making to organizations providing aid to Palestinians, the latest escalation in a dispute that saw the artist booted from Ed Sheeran’s U.S. tour.

On Wednesday, Macklemore, whose real name is Benjamin Hammond Haggerty, said in a statement on Instagram that he would donate $1 million in his net earnings from Sheeran’s Loop Tour to six organizations supporting Palestinians.

In the post, he invited Kraft to match the donation.

Kraft countered later that day, saying in a statement that Sheeran had already asked him to match the singer’s own $2 million commitment to humanitarian aid in the region “to fight this humanitarian crisis.” The exchange marked the latest clash between the artist and the billionaire owner of Gillette Stadium, which began after Macklemore made pro-Palestinian comments during two September opening performances at MetLife Stadium in New Jersey.

At the MetLife shows, Macklemore repeatedly said “Free Palestine” and criticized Israel’s conduct in Gaza.

Several advocacy groups then criticized Macklemore, and the Israeli American Council called for him to be removed from the tour.

Macklemore, for his part, said his criticism of Israel shouldn’t be interpreted as criticism of Jewish people.

In a Monday Instagram post, Macklemore said Sheeran told him personally that Kraft had barred him from Gillette Stadium following the MetLife shows, and that he had rallied other stadium owners to take the same position.

Kraft later confirmed that he would not allow Macklemore to perform at Gillette, saying the decision was based on Macklemore’s recent actions and what Kraft described as “a broader history of antisemitic rhetoric and imagery” that he said “has been deeply offensive and hurtful to the Jewish community.” Messina Touring Group, which is promoting the tour, also confirmed in a statement to multiple outlets that several venues said having Macklemore in the lineup was a red line and, as such, the promoter removed him from remaining U.S. tour dates.

Messina Touring Group has not yet responded to Fortune’s request for comment.

“Taking a side can cost you.

Money, brand deals, sponsorships, festivals, private shows, relationships and access.

I’ve lost all of those things.

But there is no neutral position between the oppressor and the oppressed,” Macklemore wrote in his Instagram post Monday.
