New revelations about the security of Hillary Clinton’s private emails are undermining congressional confidence in FBI Director James Comey’s testimony from July, when he said Clinton’s server was never breached by the hacker known as Guccifer.

Over the weekend, a report broke that Clinton’s files were in fact stolen by the Romanian hacker, and then stolen by other hackers from Guccifer. That has some lawmakers openly worried that foreign nationals are about to receive Clinton’s data, if they haven’t already.
