"You'll have to ask Michael Cohen," Trump said. "Michael's my attorney, and you'll have to ask Michael."
Another reporter then asked the president: "Do you know where he got the money to make that payment?"
"No," Trump said. "I don't know."
That reporter then asked: "Did you ever set up a fund of money that he could pull from?"
Trump ignored the question and turned to another reporter who asked the president to repeat comments he made earlier in his visit.
Trump's answers mark his first public commentary on the payment to Daniels, who has filed a lawsuit against Trump asking the court to declare her non-disclosure agreement reached in the final days of the 2016 presidential election invalid because the then-Republican candidate never signed it.
Daniels said in a 60 Minutes interview last month that she was threatened for attempting to tell her story publicly and accepted the money from Cohen because she was scared for her family. She says she had a sexual affair with Trump in 2006.
Michael Avenatti, Daniels's attorney, responded quickly yesterday on Twitter to Trump's remarks.
"We very much look forward to testing the truthfulness of Mr Trump's feigned lack of knowledge concerning the $130k payment as stated on Air Force One," he tweeted. "As history teaches us, it is one thing to deceive the press and quite another to do so under oath.
