This week, U.S. Senator Thom Tillis (R-Cornelius NC) and several of his colleagues from both sides of the isle, members of the Senate NATO Observer Group, sent a letter to Biden urging him to use this week’s diplomatic talks at the NATO-Russia Council meeting to deter Russian dictator Vladimir Putin from further invading Ukraine and make clear that the U.S. will not accept Putin’s demands to dictate NATO’s decision-making.
