SALT LAKE CITY (AP) — Former U.S. Rep. Mia Love of Utah, a daughter of Haitian immigrants who became the first Black Republican woman elected to Congress, died Sunday.

She was 49.

Love’s family posted news of her death on Love’s X account.

Love had been undergoing treatment for brain cancer, and her daughter said earlier this month that the former lawmaker was no longer responding to treatment. She had been receiving immunotherapy as part of a clinical trial at Duke University’s brain tumor center.

Love entered politics in 2003 after winning a seat on the city council in Saratoga Springs, a growing community about 30 miles (48 kilometers) south of Salt Lake City. She later became the city’s mayor.

In 2012, Love narrowly lost a bid for the House against the Democratic incumbent, former Rep. Jim Matheson, in a district that covers a string of Salt Lake City suburbs.

She ran again two years later and defeated first-time candidate Doug Owens by about 7,500 votes.

Love didn’t emphasize her race during her campaigns, but she acknowledged the significance of her election after her 2014 victory. She said her win defied naysayers who had suggested that a Black, Republican, Mormon woman couldn’t win a congressional seat in overwhelmingly white Utah.
