CHARLESTON, S.C. — Nikki Haley, the former South Carolina governor and United Nations ambassador, officially entered the race for president on Tuesday, a well hinted-at move that is likely to leave her the lone formal Republican challenger to former President Donald J. Trump for many weeks, if not months, as other potential 2024 rivals bide their time.
By announcing early, Ms. Haley, 51, who called for “generational change” in her party, seized an opportunity for a head start on fund-raising and to command a closer look from potential Republican primary voters, whose support she needs if she is to rise from low single digits in early polls of the G.O.P. field.
She made the announcement in a video, vowing to take on adversaries both foreign and domestic.
“Some people look at America and see vulnerability. The socialist left sees an opportunity to rewrite history. China and Russia are on the march. They all think we can be bullied, kicked around,” Ms. Haley said. “You should know this about me: I don’t put up with bullies. And when you kick back, it hurts them more if you’re wearing heels.”
This is a developing story and will be updated.
