Sen. Lindsey Graham (R-S.C.) said Tuesday that the Russian invasion into Ukraine has its roots in Benghazi.

It started with Benghazi. When you kill Americans and nobody pays a price, you invite this type of aggression. #Ukraine — Lindsey Graham (@GrahamBlog) March 4, 2014

Russia, of course, undertook a similar action in Georgia over four years before Benghazi. Graham's comment arrives two days after he told CNN's "State of the Union" that President Barack Obama "needs to do something."

"Stop going on television and trying to threaten thugs and dictators," Graham said of Obama. "It is not your strong suit. Every time the president goes on national television and threatens Putin or anyone like Putin, everybody's eyes roll, including mine. We have a weak and indecisive president that invites aggression."

Conservative blogger Michelle Malkin did not appear to be pleased with Graham's tweet, telling him to "just stop" with that kind of approach.

UGH. @grahamblog , you are an embarrassment to all who truly care about Benghazi. Just stop==> https://t.co/CGBxaLVebu — Michelle Malkin (@michellemalkin) March 4, 2014
