DURANT, Okla. (KTEN) — Choctaw Nation Chief Financial Officer Martin Tucker has been appointed to the Treasury Tribal Advisory Committee.

Created in 2014, the seven-member group advises the US Secretary of the Treasury on tax issues involving Native American tribes.

"This is a process that has been going on, obviously, literally, for hundreds of years," Tucker explained. "We're just trying to keep it in the right vein, if you will."

Tucker expects much of his upcoming work to focus on Tribal corporations, and whether or not the federal government should be able to tax their activity. It is a long-standing debate.

"The Tribal stance has always been — and there's treaty law to support this — that activity is not taxable by the United States government," he said. "The United States government, of course, says, 'Any activity that goes on within our borders, we're going to tax,' because that's how they generate revenue."

One Choctaw Tribal member is glad the tribes and federal government are working together, but says more could be done.

"They need to have more people that maybe will get together and talk about things, and figure all these things out, because some of the things aren't working out for the tribes," Elaine Harper said.

Oklahoma state Sen. David Bullard (R-District 6) and US Sen. Markwayne Mullin (R-Oklahoma) both wrote letters of support for Tucker's appointment.

And if that name sounds familiar... Tucker also serves as the mayor of Durant.
