U.S. President Donald Trump's attorney, Rudy Giuliani, said on Sunday he would not rule out the possibility that payments were made to women other than porn star Stormy Daniels to get them to stay silent about allegations against Trump.

Giuliani told ABC's "This Week" that he had no knowledge of whether former Trump attorney Michael Cohen had other payments, but he said: "I would think if it was necessary, yes. He (Cohen) made payments for the president or he's conducted business for the president."

Giuliani called the $130,000 Cohen paid to Daniels in 2016 a "nuisance payment." Daniels alleges that she had a sexual encounter with Trump in 2006. Trump has denied Daniels' allegations.
