President Donald Trump to stop in SC Monday to campaign for Gov. Henry McMaster | The State

A day before the state's Republican gubernatorial runoff election, President Donald Trump will stop in South Carolina to rally support for Gov. Henry McMaster's campaign against political newcomer John Warren.

In a separate trip, Vice President Mike Pence also will campaign for the Richland Republican in the Palmetto State on Saturday.

McMaster's campaign confirmed both stops late Tuesday, adding further details will be released Wednesday.

The New York Times was the first to report both campaign stops.

"President Trump and Vice President Pence are changing the world, and we couldn’t be more excited to have their support," McMaster said in a statement Tuesday. "That they are both willing to come and campaign to keep South Carolina moving forward is a testament to the success of our great state, to the things we’ve accomplished over the last few years, and to the strength of our people."

Monday, Trump will make his stop in Columbia, lending his prestige to one of the earliest statewide Republican elected officials to endorse Trump's 2016 run for the White House ahead of the pivotal S.C. primary.

The location for Pence's campaign stop was not immediately available. However, The Associated Press reported Tuesday that a source close to McMaster said Pence will stop in Myrtle Beach.

In October, Trump stumped for McMaster at a Greenville fundraiser, referring then to the governor as “my friend, my compatriot, who worked with me so hard.”

The two spoke by phone Monday.

In the buildup to last week's GOP primary, McMaster leaned heavily on his support from Trump.

But that support could not push him past a runoff, leaving him to face Warren on Tuesday.

Since the primary, Warren has picked up endorsements from two of his opponents and other GOP leaders.

McMaster and Warren will face each other in a televised debate Wednesday in Newberry.

In an email Tuesday, Warren sought to tie himself closer to Trump than his opponent.

"This campaign is about who has the best vision to clean up corruption in Columbia and hold state government accountable to the taxpayers," he said. "As the conservative outsider in this race, I am committed to shaking things up and draining the swamp in Columbia like President Trump is doing in Washington."

Meanwhile, in recent months, McMaster has advocated for Trump to receive the Nobel Peace Prize for his efforts at nuclear disarmament with North Korea.

This week, he also defended the Trump administration's policy of separating children from parents as they cross the border into the United States.

Trump's visit to the Palmetto State Monday could be a show that he is feeling confident about his standing in South Carolina, particularly after veteran lawmaker U.S. Rep. Mark Sanford of Charleston was defeated in his GOP primary last week against state Rep. Katie Arrington, The Times reports.

With just a handful of hours left until polls closed in the primary, Trump typed up a last-minute tweet, throwing his support behind Arrington.
