"We want people to know that this is going on, that we're tired of our sisters going missing, our mothers, our aunts, our grandmothers," said Angel Young, of Bismarck, a member of the Standing Rock Sioux Tribe.

Seaboy-McNeil, also a member of the Standing Rock Sioux Tribe, said the rally was held to bring a "sense of urgency" and ask Cramer to see that the act passes before Congress adjourns for the year.

"He gives a great speech and everything, but we just need more action, especially now," Seaboy-McNeil said.

Heitkamp has said on social media that Savanna’s Act is being "blocked" by Rep. Bob Goodlatte, R-Va., who is chairman of the House Judiciary Committee.

A House Judiciary Committee aide said the committee has been working with the Department of Justice and other stakeholders to address issues with the language of Savanna’s Act. The aide did not elaborate on what the concerns are.

Goodlatte’s office has not responded to Tribune requests to interview the congressman.

Sen. John Hoeven, R-N.D., said Tuesday that he's not sure where the legislation is at in the House, but is "willing to help out if (he) can."
