Speaker Mike Johnson (R-LA) called for the United States to use “every means possible” to stop Russia’s advance in Ukraine after Alexei Navalny, a top Putin critic, died in prison under mysterious circumstances.

Johnson has made similar declarations in the past. Before becoming speaker last October, he flatly stated that “Ukraine has to prevail” against Russia. But he also has fueled doubts about his commitment to further aid to the embattled ally, demanding “accountability” over how funds are spent and refusing a vote until Congress reaches an agreement on border security.
