White House officials complained that Europe is hindering efforts to end the conflict between Russia and Ukraine, and "Trump is considering temporarily withdrawing from diplomatic mediation."

According to the US news website Axios, senior officials in the White House believe that some European leaders, while publicly supporting US President Trump's efforts to end the Russia-Ukraine conflict, are trying to undermine the progress made since the meeting between US and Russian leaders in Alaska. The White House has asked the Treasury Department to prepare a list of possible sanctions that Europe may impose on Russia. The report states that it has been two weeks since the summit between Trump and Russian President Putin, but there has been no clear progress in ending the conflict. Some members of the Trump team believe that European allies should be held responsible for this. Officials say that the White House's patience is running out, and Europeans cannot delay the conflict while making unreasonable demands and expecting the US to bear the cost. A senior White House official revealed that Trump is seriously considering temporarily withdrawing from diplomatic mediation until one or both sides in Russia and Ukraine show greater flexibility. The report also states that some senior European officials are surprised by the criticism from the US side.
