Paul Kirk (D-Mass.), a onetime Democratic National Committee chairman, on Thursday.

Kirk praised the Vermont senator's "outspoken and courageous leadership, his candid and consistent pledge of allegiance to that All-American ideal," at a press conference at Dartmouth University.

"I am proud to be here to join this 'untiring effort'; and, as a former chairman of the National Democratic Party, to endorse Bernie Sanders for our party’s nomination for President of the United States of America," he added.

Kirk served the head of the DNC from 1985 to 1989 and was tapped to serve out the rest of Sen. Edward Kennedy's (D-Mass.) term after his death in 2009.

Having been a former head of the Democratic Party, he is eligible to vote for Sanders as a superdelegate at the Democratic nominating convention in July.

In the 2008 race, Kirk backed then-Sen. Barack Obama (D-Ill.) over Hillary Clinton in the primary race.
