Donald Trump returns to North Carolina without Mark Robinson, the GOP gubernatorial nominee and one of his top surrogates, following a CNN report about Robinson's alleged posts on a pornography website's message board. Robinson has denied writing the posts, but Trump's campaign has distanced itself from him. Democrats have seized on the opportunity to highlight Trump's ties to Robinson, with billboards and a new ad from Vice President Kamala Harris' campaign. North Carolina is seen as a winnable state for Democrats this fall.
