During an interview with former Deputy National Security Adviser Ben Rhodes on MSNBC's Inauguration coverage on Wednesday, host Nicolle Wallace discussed the dangers of "echo chambers" and said that it would be her policy "that a Republican must assert the truth before they're allowed to share any other views." And that if we can guard against counterfeit currency, "we should be able to protect against fake news that we now know has the potential to kill people, as it did two weeks ago."
