Civil rights icon and Democratic Party elder John Lewis Wednesday defected from Hillary Clinton to Barack Obama, in a hugely symbolic blow to the former first lady's White House campaign.
The 68-year-old Democratic "superdelegate" made his decision after a period of public agonizing, but said he wanted to be on the side of history.
"John Lewis is an American hero and a giant of the civil rights movement, and I am deeply honored to have his support," Obama said in a statement.
The veteran Georgia congressman is one of the 795 party luminaries and lawmakers who can vote how they like at the party convention and may have a vital say in sealing the presidential nomination.
Buoyed by his wins in 11 nominating contests in a row, Obama has eroded Clinton's lead in the superdelegate count heading into pivotal nominating contests on Tuesday in Texas and Ohio.
"Something is happening in America," Lewis said.
"There is a movement, there is a spirit, there is an enthusiasm in the hearts and minds of the American people that I have not seen in a long time, since the (1968) candidacy of Robert Kennedy," he said.
"The people are pressing for a new day in American politics, and I think they see Senator Barack Obama as a symbol of that change."
Lewis said he had a "deep and abiding love" for Clinton and her husband, ex-president Bill Clinton, and said the New York senator was a "brilliant and capable candidate."
