COLUMBIA, S.C.— Donald Trump made his first campaign trip of the 2024 presidential race, stopping in crucial early-voting states New Hampshire and South Carolina, as he worked to brush back calls from some Republican insiders and voters for a new party leader. “I’m more angry now and I’m more committed now than I ever was,” he said at the New Hampshire GOP’s annual meeting in Salem, N.H., on Saturday. Then in Columbia, flanked by state leaders, including Republican Gov. Henry McMaster, the former president said “the 2024 election is our one shot to save our country and we need a leader who is ready to do that on day one.”
