Presidential hopeful Bernie Sanders faced boos and groans at the She the People Presidential Forum in Houston on Wednesday after his awkward reference to Dr. Martin Luther King Jr.

The Vermont Democrat was speaking at the event — promoted as the “first-ever presidential candidate forum focused on women of color” — when he was asked how he would deal with the “rise of white supremacy” as president.

“I know I date myself a little bit here, but I actually was at the March on Washington with Dr. King back in 1963,” Sanders said, referring to the historic civil rights rally.

The crowd then burst into audible groans and booed at the senator’s pandering remark. Sanders attempted to redeem himself by mentioning his past support for a presidential candidate of color.

“As somebody who actively supported Jesse Jackson’s campaign — as one of the few white elected officials to do so in ’88 — I have dedicated my life to the fight against racism and sexism and discrimination of all forms,” he said.

Sanders’ tepid support among African American voters plagued him throughout the 2016 Democratic primary.

Exit polls showed than in South Carolina, Sanders received only 14 percent of the black vote compared to 86 percent for Hillary Clinton.
