Richard Trumka, the longtime head of the powerful AFL-CIO and a close ally of Democratic Party leaders, has died. He was 72.
Speaking before a White House event Thursday, President Biden said that Trumka died of a heart attack while on a camping trip with family.
"He wasn't just a great labor leader, he was a friend," Biden said. "He was someone I could confide in. You knew whatever he said he'd do, he would do."
