The college student who told CNN that Hillary Clinton’s presidential campaign made her a “plant” at an Iowa campaign stop now says Clinton’s staff tried to stop her from telling the media about it.

After Muriel Gallo-Chasanoff, 19, told a reporter for her Grinnell College paper a Clinton aide had given her a pre-determined question listed in a binder to ask the senator at a campaign event, Gallo-Chasanoff said a Clinton aide phoned her and asked her “not to talk about” it any more, according to the New York Post.

Clinton’s campaign first denied “planting” questions at campaign events, but later admitted to it after CNN aired an interview with Gallo-Chasanoff describing in detail how Clinton’s staff engaged her in doing so.

“They brought me to one of the senior staffers,” she said. “He showed me in his binder, he had a piece of paper that had typed out questions on it and the top one was planned specifically for a college student. It said ‘college student.”

Gallo-Chasanoff said she wanted to ask Clinton how her energy plans compared to other Democratic presidential candidates. She was told this wasn’t “a good idea” and instead she should ask Clinton about global warming.

When Gallo-Chananoff did ask Clinton about global warming as directed Clinton prefaced her response by saying: “It’s usually young people who ask me about global warming.”
