Donald Trump joked on Monday that he was willing to hold his North Carolina campaign rally outside in the rain, quipping that it would prove his hair was real.

Trump told supporters in Greenville, N.C., that he sought a larger venue for his rally in support of Dan Bishop, who is running in a special election Tuesday for the state’s 9th Congressional District.

“I was even willing to stand out in the rain and get my hair soaking wet,” Trump said, noting that the location he had in mind would have been outside the 9th district.

“But I was willing to do it. I would’ve taken it. I would’ve been very proud to have done it. It would have shown it’s my real hair at least,” he said, prompting laughter.

“It’s my hair. May not be great, but I will say it’s better than most of my friends who are the same age.”

The president’s light-hearted comments came after he was forced to scrap a tour of storm damage from Hurricane Dorian in Emerald Isle, N.C., because of severe weather. He instead received a briefing on the hurricane’s damage on Air Force One.

The Trump campaign last week relocated Monday’s rally from the Fayettesville Regional Airport to the city’s Crown Expo Center. A campaign official said the switch was caused by logistical challenges related to flights departing the airport hangar.

The president has in the past made light of his hair. He joked last October about canceling a speech to the Future Farmers of America convention because of a “a bad hair day.”

That quip came shortly after he announced he would still hold a campaign rally in the aftermath of a shooting at a Pittsburgh synagogue.
