The Taoiseach says there are no plans for an Irish ban on TikTok.
But Leo Varadkar has admitted the Government has security concerns over the Chinese-owned social media app.
It comes after politicians in America voted to force the app's owners to sell it, or face a US ban.
The US House of Representatives has passed legislation which could ban the video-sharing platform if it doesn't separate from its Chinese parent company, ByteDance.
Tiktok has its European base in Dublin, and Leo Varadkar says there are no plans for a similar ban in Ireland or the EU.
But speaking in Washington, on his St. Patrick's visit, the Taoiseach claims there are security issues with Tiktok.
"We have some concerns around security and we've put in place advice and protocols around that.
"But there are no proposals to have a ban in the European Union or Ireland. Obviously what the US decides to do here is a matter for themselves".
CEO of TikTok, Shou Chew, is vowing to fight back against a potential US ban, and had this message for the app's users.
"We will not stop fighting and advocating for you. We will continue to do all we can, including exercising our legal rights to protect this amazing platform that we have built with you. We believe we can overcome this together".
