Several of Mr. Trump’s top surrogates — including his son Donald Trump Jr., his former spokeswoman Sarah Huckabee Sanders and the governor of Florida, Ron DeSantis — were scheduled to speak at the three-day conference, which was held by a pro-Trump group, American Priority, at Trump National Doral Miami. Ms. Sanders and a person close to Mr. Trump’s son said on Sunday that they did not see the video at the conference.
Stephanie Grisham, the White House press secretary, said on Twitter Monday that while Mr. Trump has not seen the video, “based upon everything he has heard, he strongly condemns” it.
