Sen. Mike Lee, R-Utah, and Sen. Ted Cruz, R-Texas, joined the Senate floor to participate in the filibuster launched by Sen. Rand Paul, R-Ky., against the idea that President Obama can order drone strikes on American citizens in the United States.

“The issues that we are discussing today are profound to the American people,” Lee said, arguing that Americans shouldn’t be killed “capriciously” in a drone strike. “The issue here is the sanctity of human life.”
