Cherokee Chief calls for Sen. Brown’s apology

BOSTON (WHDH) -- Senator Scott Brown has warned his camp after video surfaced allegedly showing members of his staff and supporters chanting war cries and doing tomahawk chops.

The Brown supporters were mocking Elizabeth Warren's claim of having Cherokee heritage.

A democratic political organization has also posted a second video showing Brown speaking to supporters while war whoops can be heard in the background.

Brown's press secretary has released a statement, saying:

"Senator Brown has spoken to his entire staff - including the individuals involved in this unacceptable behavior - and issued them their one and only warning that this type of conduct will not be tolerated."

Bill John Baker, Principal Chief of the Cherokee Nation, said, “We need individuals in the united states senate who respect Native Americans and have an understanding of tribal issues. For that reason, I call upon Senator Brown to apologize for the offensive actions of his staff and their uneducated, unenlightened, and racist portrayal of native peoples.”

Elizabeth Warren has been unable to document her heritage.
