No one knows what Democrats mean when they talk about “border security,” but thank God White House adviser Stephen Miller was on TV to call it what it is: B.S.

Democrats regularly make it clear what they believe: Anyone who shows up at the southern border has a right to enter. But because that’s not a popular concept, they instead cover up by pretending to advocate for “border security.” It’s a deceit, and Miller laid it bare on Thursday night in an exchange on CNN with Wolf Blitzer. Every journalist in Washington should watch it.
