Redford apologized Wednesday in a hastily-called news conference at the Alberta legislature where she took no questions from reporters.
"I want to sincerely apologize to Albertans for these costs," she said. "And I have put in place measures to make sure that this never happens again."
Redford said that she has heard from people with strong opinions on both sides of the issue. However, she says questions about the trip have become a distraction from her government's agenda.
Shortly afterwards, Redford sent out a tweet apologizing to Albertans, with a link to a written statement.
