Rosie O'Donnell is guest-hosting Jimmy Kimmel Live this week, marking her first appearance as a talk-show host in almost 30 years [1].

The return signals a high-profile comeback for O'Donnell, who was once a dominant force in daytime television. Her appearance on a late-night platform provides a new venue for her public commentary during a period of significant political transition in the U.S.

O'Donnell, 64 [2], is filling in for Jimmy Kimmel. This stint marks a departure from her recent activities, including her move to Ireland. O'Donnell said she moved after reading Project 2025 and following the election of Donald Trump [1]. Other reports noted she left the U.S. after Trump returned to the White House [3].

While this week's appearance focuses on the late-night format, O'Donnell has been linked to other television returns. Reports indicate she will return to The View for its 30th anniversary [4]. Some sources suggest she may return to that program specifically as a guest host for season 30 [5].

During her time on Jimmy Kimmel Live, O'Donnell has addressed the current political climate. She mocked Donald Trump during her appearance, though she spent limited time focusing on him [6]. This measured approach differs from the more confrontational style she employed during her previous tenure in daytime television.

The return to the host's chair comes after years of intermittent appearances in the media. By stepping into the role of guest host, O'Donnell re-establishes her presence in the American entertainment landscape while maintaining her residence abroad.

O'Donnell's return to the host's desk suggests a strategic re-entry into U.S. media. By guest-hosting rather than returning to a permanent role, she can maintain her personal life in Ireland while leveraging her brand to comment on the current administration and the political shift represented by Project 2025.
