White House counselor Kellyanne Conway criticized Ocasio-Cortez in a Tuesday interview with Fox News for calling White House Chief of Staff John Kelly a liar.

“[Kelly] is in his fifth decade of public service, and this country owes him a debt of gratitude, not the nonsense that has been spewed about him recently from the left, and from this 29-year-old congresswoman who doesn’t seem to know much about anything when you ask her basic concepts about the economy, or the Middle East, or military funding,” Conway told Fox News’ Bill Hemmer.
