Republican presidential candidate Nikki Haley is taking a swipe at primary rival and former President Trump with a mobile billboard about his age, as he starts campaigning in South Carolina ahead of the upcoming primary.

The billboard will pass through the Myrtle Beach area Saturday and will stop outside of Trump’s rally while showing a video of both Trump and President Biden seemingly getting confused during speeches and mumbling during public remarks, the Haley campaign confirmed to The Hill.

The video is part of the campaign’s “Grumpy Old Men” series against the two party front-runners and was originally run as an ad, which The Hill first reported on. The video will specifically highlight moments when Trump confused Haley for former Speaker Nancy Pelosi (D-Calif.) and mixed up Sioux City, Iowa, with Sioux Falls, South Dakota. 

Haley, the former governor of South Carolina, said Friday that both Trump and Biden would use the Oval Office, if they secure their second term, as a “taxpayer-subsidized nursing home.” 

Her campaign has intensified the scrutiny around Trump, as the former president still leads her by double digits in her home state ahead of the Feb. 24 primary. Currently, Trump leads Haley by roughly 32 points, according to the The Hill/Decision Desk HQ’s polling average.

Haley’s camp has vowed to stay in the race longer, but she faces an uphill climb to secure a primary victory in her home state, where support for the former president has not wavered. Trump has secured endorsements from top politicians in the Palmetto State, casting further his influence over the state’s voters ahead of the contest. 

Haley proposed a mental competency test for politicians over the age of 75 nearly a year ago, and has called for a new generation of leadership in her party. 

Trump has hit back at Haley for going after his age, saying ahead of the New Hampshire primary that he would score higher on a cognitive test than her.
