In a packed day of shuttle diplomacy following negotiations in Abu Dhabi, Kushner and fellow envoy Steve Witkoff held over four hours of talks with Putin in the Kremlin before jetting to debrief Zelensky in Dublin.

As they spoke to journalists on the tarmac of a military airbase in Ireland, the main piece of progress touted by the Ukrainian leader and US President Donald Trump's representative was that European negotiators would be at the table for future talks.
