WILMINGTON, N.C. — Donald Trump returns to North Carolina on Saturday, stumping in the southern battleground state that both Democrats and Republicans are treating as increasingly critical to victory in November.

But Trump will be campaigning in Wilmington, along the state's southern coast, without Lt. Gov. Mark Robinson, the GOP gubernatorial nominee and one of the former president's top surrogates in the state, following a CNN report about his alleged posts on a pornography website’s message board. Two people familiar with the matter who spoke on condition of anonymity said Friday that Robinson was not scheduled to attend the Wilmington event.

Robinson has denied writing the posts, which include lewd and racist comments, saying Thursday that he wouldn’t be forced out of the race by “salacious tabloid lies.” Trump's campaign has appeared to distance itself from Robinson in the wake of the CNN reporting, which the AP has not independently verified, saying in statement to the AP that Trump “is focused on winning the White House and saving this country" and calling North Carolina “a vital part of that plan," without mentioning Robinson.

While Robinson won his GOP gubernatorial primary in March, he’s been trailing in several recent polls to Democratic nominee Josh Stein, the state’s attorney general. State Republican officials have stood by Robinson, whose decision to keep campaigning could threaten GOP prospects in other key races, including Trump’s efforts in a battleground state he previously won twice.

Democrats have seized on the opportunity to highlight Trump's ties to Robinson, with billboards showing the two together, as well as a new ad from Vice President Kamala Harris ' campaign highlighting the Republican candidates' ties as well as Robinson's support for a statewide abortion ban without exceptions. According to Harris' campaign, it's their first ad effort related to tying Trump to a down-ballot race.

A Republican has carried North Carolina in every general election since 1976 save one, when Barack Obama won the state in 2008. Trump won there in both his previous campaigns but by less than 1.5 percentage points over Democrat Joe Biden in 2020, the closest margin of any state that Trump won. That's part of why Democrats see the state as winnable this fall.

With neither Senate seat up for grabs, the gubernatorial contest has been North Carolina's marquee down-ballot race this year. Robinson has become a natural top surrogate for Trump in the state and a frequent presence at campaign events there, appearing with the nominee as recently as an event last month in Asheboro. Trump has long praised Robinson, who is Black, referring to him as “Martin Luther King on steroids."

Endorsing Robinson ahead of the GOP gubernatorial primary, Trump continued: “I think you’re better than Martin Luther King. I think you are Martin Luther King times two.”

While more visits have been made by presidential contenders to the Rust Belt battlegrounds of Pennsylvania, Michigan and Wisconsin, both Harris and Trump have made multiple trips to North Carolina, highlighting the state’s importance. Following Biden’s departure from the race in July, Trump held his first large-scale rally there, turning his full focus toward Harris.

Wilmington is home to New Hanover County, which Biden won in 2020. But his margin over Trump in the county was among his slimmest in the state.
