Taoiseach Micheál Martin is in lockdown in Washington and is isolating for at least five days and likely won't leave until March 26 after testing positive for Covid-19.
According to America's public health guidelines, once a person tests positive for Covid-19, they can not travel for 10 days.
In a chaotic turn of events, Mr Martin was forced to cancel his trip to the White House on St Patrick’s Day and instead held a virtual meeting again with US President Joe Biden.
