Trudeau issued a statement on Twitter later Sunday saying, "My thoughts are with my friend and colleague @SeamusORegan tonight, and he has my full support."
O'Regan, who hosted CTV's Canada AM for nearly a decade, announced from his Twitter account that he had checked into the program over the holiday break.
O'Regan says he made the decision after consulting with family and plans to return to his duties as an MP for St. John's South-Mount Pearl before Parliament resumes later this month.
He also noted that he'd have more to say on the matter in the future, but asked for privacy until then.
O'Regan's husband expressed his support shortly after the announcement was made online.
