The Taoiseach has said there's been an absence of moral leadership in the United States after the killing of George Floyd.
Leo Varadkar has also hit out at the overt and insidious racism many people experience in Ireland.
He was also critical of the response to the protests from Donald Trump.
"We've sen genuine revulsion at the heavy handed responses towards peaceful protesters and journalist.
"And we've witnessed the absence of moral leadership, and words of understanding, comfort or healing, from whence they should have come.
"It is right to be angered by injustice - racism too is a virus, transmitted at an early age, perpetuated by prejudice, sustained by systems, often unrecognised by those whom it infects."
