Nikki Haley dropping out of GOP presidential race after multiple losses to Donald Trump on Super Tuesday

Former U.S. ambassador to the United Nations Nikki Haley is suspending her bid for the Republican presidential nomination, according to CBS News sources familiar with the matter.

Haley is to deliver remarks to the press Wednesday morning in Charleston, in her home state of South Carolina.

Sources with direct knowledge of Haley's planned remarks tell CBS News she will not endorse former President Donald Trump during her remarks. However, CBS News confirms that she will encourage Trump to "earn the support" of her Republican backers and independent voters who favored her during the GOP primary.
