AKIPRESS.COM - The seven-year-old girl whose phone call with President Donald Trump on Christmas Eve went viral has said she still believes in Santa Claus.

Mr Trump threw doubt on the existence of Santa when he asked Collman Lloyd if she still believed in Father Christmas, BBC reports.

After learning the girl's age, the president asked: "At seven, it's marginal, right?"

"Yes, sir," the girl replied. She later admitted she did not know the word's meaning, the Post and Courier reports.

Collman, from Lexington in South Carolina, also told the newspaper that she was glad to be able to talk with the US president.

"I was like, 'wow'. I was shocked. It wasn't really (nerve-wracking), I just had to think of what the truth was."
