Sen. Mike Lee (R-Utah) said on Tuesday that President Barack Obama's drone policy was "fraught with constitutional problems."
"I really don't like the legal justification because it's not a legal justification at all," Lee told Ingarahm. "There's no legal analysis in it at all."
Ingraham asked Lee for his reaction to an interview conducted by The Huffington Post with House Minority Leader Nancy Pelosi (D-Calif.), where she commented that "it just depends" whether the public should be informed of the targeted killing of a U.S. citizen.
"I'm nervous when people say 'it just depends,'" Lee told Ingraham. "The legitimacy of the answer depends on what it depends upon. ... They've got to finish the sentence."
Lee told Ingraham that "one can fathom" a situation where an American citizen became the target of U.S. armed forces because he or she "engaged in an act of war against the United States." But he argued that justifying the "execution" of American citizens on the basis that they were outside of the United States was "a problem."
During his State of the Union address on Feb. 12, Obama pledged that the administration would offer more transparency on the drone program.
