"He would call all the time," Munyan said, adding that the calls occurred between 2006 and 2007, the time frame in which Daniels alleges she was having an affair with Trump.
"That man can talk about nothing for hours," Munyan said.
He said the conversations between Daniels and Trump were businesslike.
"It was always about business and what her goals are," Munyan said.
Munyan, a professional photographer, is one of the four people named in the nondisclosure agreement that was signed by Trump's longtime personal attorney, Michael Cohen, and Daniels, whose legal name is Stephanie Clifford. The agreement was signed in October 2016, just weeks before the presidential election, to keep Daniels from talking about her alleged affair with Trump.
Daniels also received $130,000 from Cohen to seal the deal, before the election. On Monday, in a letter from her attorney, Daniels offered to give that money back to Trump if he would let her speak freely and make the agreement null and void. Neither Trump nor his attorney responded to the offer, according to Daniels' attorney Michael Avenatti.
Last month, Cohen admitted to making a payment to Clifford, writing in a statement: "Neither the Trump Organization nor the Trump campaign was a party to the transaction with Ms. Clifford, and neither reimbursed me for the payment, either directly or indirectly."
Munyan, a professional photographer who has shot celebrities and public figures for 25 years, met Daniels on a photo shoot in 2005. He said they bonded over the facts that they are both from Louisiana and love horses.
Munyan said that no matter what people who don't know her think, Daniels is "very intelligent, smart and very articulate." And, he says, most of all "she is funny."
