He says Gardaí have legal powers.
The Minister for Health is urging the people of Laois, Offaly and Kildare to observe the county boundaries rule.
While residents are free to cross boundaries for work, childcare or to access healthcare, they should stay within their county at all other times.
This is the case even for towns on county boundaries like Graiguecullen, Horseleap and Portarlington because the lockdown is an essential public health measure.
Minister Donnelly says Gardai have legal powers to turn people back but he'd prefer if people acted in solidarity:
