Carter Flash 90

Former President Jimmy Carter was rushed to a Winnipeg hospital on Thursday, after he became severely dehydrated at a worksite for Habitat for Humanity, a charitable organization which uses volunteer labor to build housing for low income families. Carter has been involved with the group since the 1980s.

The 39th president reportedly became “dehydrated working in the hot sun,” Habitat for Humanity said in a statement.

"President Carter told us he is okay and is being taken offsite for observation. He encourages everyone to stay hydrated and keep building," an organization spokesperson said.

The former president and his wife, Rosalynn, travelled to Canada for a week-long tour of building projects around the country.

In August 2015, Carter underwent surgery to remove a “small mass” on his liver. Seventeen days later, however, Carter revealed that he had been diagnosed with melanoma, which had metastasized to his brain, and that he was undergoing treatment. In December 2015, Carter stated that no evidence of cancerous tumors had been found following his treatment.
