Frontline American politician Joseph Lieberman has died. 

Family members said in a statement that Mr Lieberman, who served four terms in the United States Senate, passed away on Wednesday after a fall. He was 82. 

Mr Lieberman, from Connecticut, was the Democratic vice presidential candidate to former Vice-President Albert Gore in the 2000 election. The duo lost the hotly-contested election to George W. Bush and Dick Cheney, who went on to serve two terms.

The Jewish politician was very public about his attachment to his Jewish faith. 

Mr Lieberman “was a Jew from my hometown. He prayed at the same synagogue my family belongs to in Stamford. He prayed at the same synagogue I went to periodically in college. I saw him walking to the Capitol a few times on Saturday from his home in Georgetown. It was very cool to see a[n] observant Jew in prominent public office,” Jake Sherman, founder of Punchbowl News, tweeted in the former senator’s memory.

Mr Lieberman retired from politics after serving his fourth term in the Senate in 2013. The former senator lost the 2006 Democratic primary election but managed to win the election under an independent ticket as an Independent Democrat, according to Ballotpedia. He scored 49.71 per cent of the vote, defeating Ned Lamont. 

In recent months, Mr Lieberman had championed a so-called no-label movement to challenge the Republican and Democratic parties in the U.S., saying many people had become disillusioned with the two dominant political parties in recent decades.
