Alberta Premier Danielle Smith's office says her recent comments about chemtrails don't mean she believes the United States government is spraying them in the province.

"The premier was simply sharing what she has heard from some folks over the summer on this issue," Smith's spokesperson Savannah Johannsen said Tuesday in a statement.

Smith faced criticism after she spoke about chemtrails this past weekend at a United Conservative Party town hall in Edmonton.

During the town hall, in response to an audience member's concerns about chemtrail spraying over Edmonton, Smith said, "The best I have been able to do is talk to the woman who is responsible for controlling the airspace, and she says no one is allowed to go up and spray anything in the air."

When the crowd hooted and booed, Smith said, "That's what she's told me."
