Sen.
Facing a Republican primary challenge, the second-term senator, considered moderate on some issues, including immigration, has echoed calls on the right for greater investigation into the administration's handling of the Benghazi attack, which killed four Americans, including a U.S. ambassador. With the tweets, Graham doubled down on comments he made Monday night in which he called Russia's aggression "a symptom of a greater problem."
But some on the right, including conservative blogger Michelle Malkin, took issue with Graham's comparison, characterizing it as an "embarrassment to all who truly care about Benghazi." Malkin maintained her critique in a later tweet, noting that Russia invaded Georgia in 2008.
Dan Pfeiffer, White House senior advisor, tweeted that Graham's comments "jumped the shark":
GOP criticism of Pres Obama jumped the shark today when they started saying Benghazi is one of the reasons for what is happening in Crimea
