How will the US address concerns from EU countries who feel they've been sidelined in consultations about Ukraine?

According to Kurt Volker, former US Ambassador to NATO, these concerns from EU countries are not accurate. He explains that the US has been actively engaging with European partners through multiple channels, including NATO consultations, bilateral discussions, and meetings in various capitals. Volker's response indicates that rather than sidelining European allies, the US has maintained ongoing diplomatic communications regarding Ukraine through various established diplomatic mechanisms. His statement counters the perception that European nations have been excluded from important talks on the Ukraine situation.
