Over in the House, Rep. Adam Kinzinger, has emphatically endorsed a U.S. no-fly zone over Ukraine.

Former top foreign policy officials are trying to dress up the idea as a “limited” no-fly zone.

“NATO leaders should convey to Russian officials that they do not seek direct confrontation with Russian forces, but they must also make clear that they will not countenance Russian attacks on civilian areas,” reads a letter signed by, among others, Kurt Volker, the former American ambassador to Ukraine, and Bill Taylor, the former American ambassador to Ukraine implicated in the first impeachment of then-President Trump.
