Speaker of the House Nancy Pelosi plans to celebrate St. Patrick’s Day were scrambled Thursday after Irish Prime Minister Micheál Martin tested positive for COVID-19.

Watch Pelosi’s remarks in the player above.

Martin tested positive on Wednesday evening. The positive result forced him to leave early from a gala where he had already interacted with President Joe Biden and Pelosi.

Pelosi was supposed to greet Martin on Capitol Hill for the annual “Friends of Ireland Luncheon,” but those events have been reimagined as the Irish leader isolates at Blair House across the street from the White House.

Martin will sit out the “Friends of Ireland Luncheon” at the Capitol that President Joe Biden will attend.

Pelosi also praised Ukraine President Volodymyr Zelenskyy for his address to Congress and said that “he unity of the NATO alliance … has been remarkable to behold.”
