COLUMBIA, S.C. (AP) - Governor NikkiHaley will represent the former Massachusetts governor at the Pennsylvania Leadership Conference this Friday. She plans to speak on Romney's behalf during the annual, two-day conference for conservatives.
The conference's website says others planning to speak include a competitor for the Republican nomination, former Pennsylvania Sen. Rick Santorum.
Pennsylvania's presidential primary is April 24.
Haley endorsed Romney in December and campaigned with him in New Hampshire and South Carolina.
Romney came in second in South Carolina to former House Speaker Newt Gingrich, who received 40 percent of the vote to Romney's 28 percent.
Haley is also the keynote speaker Tuesday at a National Republican Congressional Committee dinner in Washington.
