WATCH: President Biden hosts White House Shamrock presentation celebrating St. Patrick’s Day

U.S. President Joe Biden had to settle for meeting virtually Thursday with Irish Prime Minister Micheál Martin after the visiting leader’s positive test for COVID-19 scrambled plans to mark St. Patrick’s Day at the White House.

Biden and the First Lady Jill Biden hosted a White House reception for Thursday evening, but Martin did not participate in person. But the traditional crystal bowl of shamrock did.

“As two nations that have fought for freedom, we recognize the courage and determination of the Ukrainian people who defend their liberty now,” Biden said. “We’re determined, though, to help the Ukrainian people bring an end to Putin’s brutal assault and restore peace to the Ukrainian people.”

“Our hearts are open and our arms are open to help more than three million Ukrainian refugees have already fled Putin’s onslaught,” the president said.

“We are reminded by the appalling events in Ukraine that freedom and democracy can never be taken for granted,” Martin said.

During an earlier, virtual, Oval Office meeting Biden and Martin joined to condemn Russia’s invasion of Ukraine, which has jolted the world and brought the U.S. and its European allies to unite in condemnation and in placing stiff sanctions on Russia.

The virtual meeting kicked off the first in a day-long set of festivities that have been reimagined after the Irish leader’s diagnosis.

Martin learned he had tested positive Wednesday evening while attending an event with Biden and Pelosi, but the White House said the president was not considered a close contact of Martin – also referred to as Ireland’s taoiseach.

This year marks the Irish-American Biden’s second St. Patrick’s Day in office, but his first with substantial in-person events after last year’s celebrations were suspended by the pandemic.
