The Irish hip-hop group Kneecap says it has begun legal action against Vince Gasparro, the Liberal parliamentary secretary who posted a video on social media announcing an apparent ban on the group entering Canada that their lawyer says caused "substantial" harm. Lawyer Darragh Mackin told Global News that a defamation case is being pursued in Ireland against Gasparro, who Mackin said was served with a notice of claim over the weekend.
