'Outnumbered' Reacts After Obama Says We're Hitting ISIS 'Harder Than Ever'

Charles Krauthammer said on "Special Report" tonight that the Obama administration's process for vetting U.S. visa applicants is "incomprehensible."

He explained that the decision to expand the examination of social media for all visa applicants was a long time coming, as the arguments against it were "ridiculous."

He said that the claim that social media screening is an invasion of privacy is absurd, because there is no invasion of privacy if screeners are looking at public postings.

"It's doubly absurd if that's in the case of a non-American outside the country, who possesses zero constitutional rights," Krauthammer said.

Judge Andrew Napolitano agreed that there is no legal or constitutional problem with looking at public postings.

As for private information, Judge Napolitano suggested that anyone who wants a visa should waive their right to privacy and hand over their cell phone for examination.

"You don't want to give us the cell phone? You don't want to waive your right to privacy? You're on your way back," Judge Napolitano said.

"And he's a libertarian!" Krauthammer remarked.
