Tulsi Gabbard said she will run for US president in 2020.
"I have decided to run and will be making a formal announcement within the next week," said the Hawaii Democrat.
Gabbard, an Iraq War veteran, currently serves on the House Foreign Affairs Committee. She is the first American Samoan and the first Hindu member of Congress.
"There are a lot of reasons for me to make this decision. There are a lot of challenges that are facing the American people that I'm concerned about and that I want to help solve," she said, listing health care access, criminal justice reform and climate change as key platform issues.
"There is one main issue that is central to the rest, and that is the issue of war and peace," Gabbard added. "I look forward to being able to get into this and to talk about it in depth when we make our announcement."
