Hillary Clinton is refusing to say whether a Clinton-Gore pin featuring a Confederate flag was part of her husband's official campaign merchandise.

Examples of the distinctive red and blue badge, from the 1992 election, are now being sold on Ebay.

It comes as politicians, including President Obama, called for the Confederate battle flag to be taken down in the state capitol, a week after a white gunman allegedly shot dead nine black worshipers at a church in South Carolina.

Many argue the flag which 21-year-old Dylann Roof, charged in the Charleston church shootings, was pictured with the Confederate, is a symbol of hatred and should be consigned to museums.

But the former Arkansas first lady has not responded to questions by The Blaze over whether she knew if the pin was part of the official campaign. She has also failed to respond to requests over whether she is opposed now, or opposed then, to an act signed by her husband honoring the Confederate flag, the website said.

Mrs Clinton weighed in on the South Carolina confederate flag debate back in 2007 and still holds the view that it should be taken down.

America's largest retailer Walmart said on Monday that it will be removing all products promoting the Confederate flag from its stores in the wake of controversy following the South Carolina shootings.

As South Carolina leaders are pushing to remove the flag that flies at the statehouse in Columbia, officials in Mississippi and Tennessee are grappling with whether to retain Old South symbols.

Mississippi voters decided by a 2-to-1 margin in 2001 to keep the state flag that has been used since 1894.

It features the Confederate battle emblem in the upper left corner - a blue X with 13 stars, over a red field.

Republican Governor Phil Bryant on Monday repeated his long-held position that the state should keep the flag as is.

'A vast majority of Mississippians voted to keep the state's flag, and I don't believe the Mississippi Legislature will act to supersede the will of the people on this issue,' Bryant said in a statement.

Democratic Senator Kenny Wayne Jones of Canton, chairman of the Legislative Black Caucus, said the Confederate emblem is a 'symbol of hatred' often associated with racial violence.

Jones said the flag represents the power structure's resistance to change during the 1960s and '70s, when civil rights activists were pushing to dismantle segregation and expand voting rights.

'We should be constantly re-examining these types of stereotypes that label our state for what it used to be a long time ago,' Jones told The Associated Press.

Since the 2001 Mississippi election, bills that proposed changing the flag have gained no traction, with legislators saying voters settled the issue.

At the Tennessee Capitol in Nashville, a bust of Nathan Bedford Forrest, a Confederate general and an early Ku Klux Klan leader, has sat in an alcove outside the Senate chamber for decades.

Democratic and Republican leaders are calling for the bust to be removed.

Craig Fitzhugh, the state House Democratic leader, said it should go to the archives or a museum and be replaced in the Capitol by a statue of Lois DeBerry, an African-American who became the first female speaker pro tempore of the Tennessee House.

Women and minorities are underrepresented in government symbols, Fitzhugh wrote.
