Sen. Bernie Sanders’ daughter-in-law ​Rainè ​Riggs died on Saturday just days after being diagnosed with cancer. She was 46.

Riggs, who was married to Levi Sanders, was diagnosed with neuroendocrine cancer​ at the University of Pittsburgh Medical Center​​, according to the obituary posted by the Lee & Martin Funeral Home in Burgettstown, Pa.

They had three children.

She and Levi Sanders met while the two worked at an emergency food shelter in Vermont.

​She died the same day her father-in-law, ​a Democratic presidential candidate, returned to Vermont after ​suffering a heart attack while on the campaign trail.

Riggs earned a doctorate in neuropsychology at the University of Vermont and started the Palliative Care Department at the Dartmouth Medical Center.

“Her last words were to tell her children how much she loved them and she was so sorry that she got sick,” her family wrote in the obituary.

“I don’t know how our family will ever get over this loss as she was loved so much. I do know that we will continue on because we have to​ ​… we promised her we would​,” it said.
