More tapes featuring Donald Trump involved in sexually explicit conversations have emerged just hours before he is due to take part in the second US Presidential debate.
Trump is already being criticised following the release of a 2005 video of him talking on an open microphone.
The recording showed the then-reality TV star speaking about groping women and trying to seduce a married woman. The video was taped only months after Trump married his third wife, Melania.
In a statement, Melania Trump called her husband's words "unacceptable and offensive to me."
"This does not represent the man that I know," she said. "He has the heart and mind of a leader. I hope people will accept his apology, as I have, and focus on the important issues facing our nation and the world."
The backlash over the video was swift and widespread.
Now the presidential nominee is under siege for sexually explicit conversations compiled from a series of radio interviews over the past 23 years.
In the interviews, with shock jock Howard Stern, Trump noted how “voluptuous” his daughter was.
The videos, aired by CNN on Saturday, also feature Trump saying that he would “have no problem” having sex with 24-year-olds, that he “couldn’t care less” if he satisfies the women he sleeps with and that “it’s checkout time” once women reach the age of 35.
He also revealed how he would use his status to barge into Miss Universe beauty pageant contestants' dressing rooms while they were changing.
Trump and Stern also talk about the nominee’s older daughter, Ivanka.
On one show 10 years ago, Stern asked whether 24-year-old Ivanka Trump has breast implants, and her father replied; “She’s actually always been very voluptuous.”
US Election 2016
With his campaign in crisis, U.S. presidential candidate Donald Trump vowed on Saturday to stay in the race despite calls from more than two dozen prominent Republicans for him to drop out following the release of a recording of him making lewd comments about women.
