"The questions were sent to me for approval; I approved of them ... I got several questions — eight of them. And the four that were chosen were the ones that I approved," she told CNN on Saturday.
When asked to confirm whether the list of questions was received from the White House, Lawful-Sanders answered in the affirmative.
On the same day, CivicMedia radio host Earl Ingram, who interviewed Biden this week, told ABC News that he was also given questions for the interview.
Ingram noted that he received a list of five questions from the US leader's team and ended up voicing four of them.
Later, CNN reported that Biden's campaign will no longer send questions to interviewers in advance.
"While interview hosts have always been free to ask whatever questions they please, moving forward we will refrain from offering suggested questions," a source was quoted as saying by the broadcaster.
