WASHINGTON (JTA) — Bernie Sanders posted a campaign video with a supporter praising him for condemning “apartheid-like” conditions among Palestinians.

“He spoke out against apartheid in South Africa when crazily that was an unpopular thing to do and even today he speaks out against apartheid-like conditions in Palestine even though it’s not popular,” Shaun King said in the video posted Monday on the presidential campaign’s Facebook page.

King, a columnist and activist, spoke at the formal launch of Sanders’ campaign on March 2. The video breaks away from King’s speech to a highlighted online CNN headline, “Bernie Sanders smashes the Israel status quo.”

Sanders, I-Vt., has been among the Senate’s most trenchant Israel critics, releasing multiple videos last year decrying Israel’s use of lethal weapons to end protests and riots on the border between the Gaza Strip and Israel.

Sanders was the first Jewish candidate to win major nominating contests when he ran for the Democratic nomination in 2016.
