Former US South Carolina Gov. Nikki Haley will announce Wednesday that she is exiting the Republican presidential race, according to sources familiar with her plans, clearing the path for former President Donald Trump, Paralel.Az reports citing CNN.

Haley had emerged as former President Donald Trump’s sole rival in the Republican presidential primary campaign, and while he rolled to victory in 14 of the 15 GOP contests on Super Tuesday, she foiled a possible clean sweep by winning in Vermont.

Across the Republican primaries on Super Tuesday, Haley won just 43 of the Republican delegates while Trump won 764.

Ahead of the South Carolina primary in February, Haley vowed to stay in the race through to Super Tuesday on March 5, saying she would continue to compete in the primary “until the last person votes, because I believe in a better America and a brighter future for our kids.”

Haley is expected to deliver remarks in Charleston, South Carolina.
